journal 1 Flight comparison

As seen on the first observation a chickadee has more of an elliptical wing and has a powerful down stroke to gain elevation and does that a few times and then will glide while loosing elevation. When walking on another field observation I saw a herring or ring-billed gull flying overhead. This sea bird has a high Aspect ratio wing and is great for gliding. The gull would flap a few times generating enough power to glide for a while. These 2 different birds have different wings that are useful to its habitat and behaviors. Since a chickadee will only move short distances it doesn't need a wing for gliding but also has a wing that will produce enough power quickly if needed to escape a dangerous situation since they sometimes feed on the ground or feeders where they run the risk of predator. For a seagull traveling long distances over the shore or ocean a High aspect ration wing provides the lift necessary to glide and saves energy by reducing the number of wing strokes.

Flight and Wing Physiology

I went out on Monday 2/17/2020 for an hour and a half starting at 12:15 pm. I was in a fairly forested area with a decent mix of deciduous and coniferous trees. It was 27 degrees Fahrenheit out and very sunny. There were occasional clouds. There was a slight northeast breeze at about 5 miles per hour with occasional stronger gusts. I was in East Montpelier around a residential property but then moved onto some recreation trails.

I started near the residential property and was having difficulty locating any birds, although I could hear distinctly 3 black-capped chickadees calling from high up in the trees. I was wondering if the reason for their timidness was because there are two domesticated cats that live on the property. They predate on birds. Further, the property is surrounded on all sides by roads, creating a very small fragment of land. For edge sensitive species or species with large ranges, this may not be ideal territory. I decided to move further away from the range of the cats and into a more continuous wooded area to see if this provided better success, and it did.

I observed 10 Black-capped Chickadees while along the trail. They traveled in groups of 2-4. They were foraging within the trees for seeds. They jumped between branches or used a few quick wing flaps to propel them to nearby branches. They had elliptical wings which allowed for easy maneuverability through these dense trees. In contrast to the Black-capped Chickadees, the singular Common Raven had fewer flaps of its wings. I saw it gliding through the air. Its wings were more like slotted high lift wings, the primary feathers splaying out towards the end of each wing. This provides better lift which they can utilize to keep them aloft while simultaneously minimizing stalling during flight due to consistent air foils created by the primaries. This allows for gliding which can be conducive to their method of foraging, including scouting for carrion among other food sources down below. This demonstrates how clear differences in wing physiology can play into niche differentiation. Smaller elliptical wings are conducive to short flight and easier maneuverability through dense vegetation while slated high lift wings are more conducive to gliding in open air.

Новый шейп-файл Санкт-Петербурга

Дорогие друзья!

Сегодня число наблюдений проекта сократилось на 117 штук. В качестве границ для проекта "Флора Санкт-Петербурга" мы загрузили два шейп-файла:

базовый Gorod Sankt-Peterburg, RU
и морской Gorod Sankt-Peterburg (adjacent sea area), RU

Это позволило исключить находки с приграничных местностей Ленинградской области, но включить узкую прибрежную полосу и акваторию Финского залива, которые не попали в базовый шейп-файл.

Field Journal 2- ID and Flight Physiology

On Monday, February 17, 2020, I went to Wheeler Nature Park in South Burlington, VT to conduct my birding walk. It was cold and windy (27 degrees Fahrenheit and wind 10 mph) but there were still some birds out and about in the sunshine. I started the walk at 2:50 pm. I was anticipating not seeing too many birds because usually they are more active around dawn and dusk when they go looking for food.
At Wheeler Nature Park, there is a good variety of different vegetation types throughout the park. I began walking from the parking lot and followed the path that heads towards the tree line. This area is very open and broken up by some patches of trees and shrubs in a few spots. As you continue down from the field along the path, the vegetation becomes thicker and there are more dense patches of vegetation. In this area there is a mix of older and younger trees that diversifies the structure of the woods. During this time, I could hear the call of a Black-capped Chickadee. I could tell by the "chick-a-dee-dee-dee-dee-dee" call exactly what species I was listening to. I tried to find the bird with my binoculars but I wasn't able to locate it. I listened for a few minutes to see if I could distinguish if there were one or two birds, but I concluded there was only one because I only heard one call.
I was continuing along the path and getting closer to the woods and more dense vegetation when I heard the sound of a Blue Jay, which sounds very distinctive to me. I think it sounds very loud and dominating and almost mean. I only heard it one time and I stood there for a few minutes waiting for it to call again but I didn't hear anything. As I turned to continue up the path into the woods, I see the Blue Jay in the understory. It was hopping from branch to branch on a white pine tree. I watched it with my binoculars for a few moments and was surprised by the size of this bird. It did not look like it had any trouble fattening up for the winter. I think that this one might have been a male because it was so big and the males are generally larger than the females.
I did not see too many more birds when I was in the woods. I think that it might have been because I was there in the middle of the day and the birds might have been resting and staying warm between their meals. As I was finishing up, I saw a group of American Robins sitting in a tree together. I could see their rusty red chests and white underbellies. They tended to stay close to each other, but we not too cautious of me once I was there for a few minutes. I saw an American Robin eating some berries on the top of a bush but I am not sure what kind of bush it was on. I saw the American Robins more in the edge habitat that surrounded the field, which made me think they might like the areas where they can easily hide but also see what is around them and if there is danger coming.
The flight pattern of the American Robin looked like very strong and swift and powerful. They use one or two flaps to propel themselves where they want to go. They have rounded wings that carry them up and down easily. I mostly observed these birds flying short distances from tree to tree.
The Blue Jay I observed hopped more than it flew, but when it did fly, it was calm and strong. It has similarly shaped wings to the American Robin, but a much larger tail. I imagine the tail helps propel them off the ground when beginning flight because the Blue Jay is bigger than the American Robin. The flying style of both of these birds was similar but I think this is because they are both songbirds around the same size. They may have similar predators they must escape from or competitors to fight over food with. The rounded wings allow them to do a variety of motions, like short flights through a field, to twisting flights through the woods, and agile movements to get to those limited food supplies.

Field Observation: ID and Flight Physiology

On February 10, 2020 from 12:30 to 2:00 pm, I walked along a snowmobile trail in Shelburne, Vermont to observe birds. The temperature was ~37 degrees Fahrenheit, and there was a fair amount of wind.

At around 12:40pm, I spotted a Black Vulture flying in the distance. It was gliding at a high altitude, and it did so by keeping its wings spread out to the sides and only flapping a couple times. Each wing stroke was very powerful and lifted the vulture higher and further. The wings of the black vulture are considered to be slotted, high lift, as the ends of the wings have finger-like feathers that work as an air foil and provides lift. It makes sense that this bird was gliding in circles because it was probably searching for food/roadkill.

Around 1:00pm, I heard black-capped chickadees calling nearby. I heard them calling and singing for approximately 30 minutes before I walked out of range. There were at least two chickadees, but there may have been more. The most frequent sound was the “cheeseburger” tune, but I also heard the classic “chickadee-dee-dee-dee” call. I wasn’t able to actually locate the chickadees because there were many trees and bushes around and they blend in well. It was fairly windy outside and the sun was not fully out, so perhaps the chickadees were staying put in the trees and trying to conserve their body heat. At night, black-capped chickadees go into controlled hypothermia and conserve their hourly metabolic expenditure. However, in the afternoon, the black-capped chickadees may have been perched in a tree cavity to stay warm and that is the reason why I wasn’t able to see them.

Around 1:45pm, I was walking close to a couple of houses and saw five American Robins flying around between the bushes and the trees. I watched the birds from a distance for a while so that they wouldn’t fly away. They were fluttering from branch to branch but would pause on a branch before they moved to another. I found it interesting that the robins were so close to the houses rather than in the trees along the more secluded path. The ground had snow on it, so I imagine the ground is too frozen for the robins to find worms. The trees and bushes that they were on looked like they had little berries/fruits left on them, so they were probably foraging for those. The berry/fruit trees are probably more likely to be planted near homes (for landscaping), so maybe that is why I saw so many robins here. From observing their wings, I think they fall under the category of elliptical, which are the default wing type, They have frayed feathers at the end of their wings, and the primary feathers are much shorter than the secondary feathers. When I walked closer, the robins took off simultaneously. I watched one bird specifically as it flew away, and it had 3-4 smooth wing beats followed by a short glide in which the wings were held tightly into the body.

February 17, 2020

I started my birding trip at around 4:00 pm on February 17th, 2020. It was a pretty sunny day, the sky was clear and it was about 32 degrees Fahrenheit. There was some wind but it was mostly blocked by the surrounding buildings. I started at Redstone campus, observing the green for a bit then started to walk towards main street. I saw a couple of European starlings fly overhead. I walked past a large bush and saw a bunch of House Sparrows in its branches. I saw a couple of rock pigeons perched on top of a building. At one point I saw an American Crow fly overhead. European Starlings seem to fly together. The ones I saw were flying together. There was only one instance where I saw a single European Starling flying alone. They flap their wings pretty quickly and don’t glide very much. Rock pigeons on the other hand flap there wings slightly slower but seem to glide even less that European Starlings. A European Starlings wings are slightly smaller and more pointed but overall they have a similar shape to that of a Rock Pigeon. I’m most likely not seeing very many birds because it is the middle of winter. Most birds likely are less active, conserving energy to keep themselves warm. Getting slightly further from areas with high human traffic as well as waiting until the weather is warmer will probably result in me seeing more birds.

Mantidflies in Florida

I'm reaching out to observers in central Florida to keep an eye out for an apparently unique mantidfly documented in that area. Here are some observations:

If you find something that looks like this, capture it, post a pic, and contact me. It may just be an unusual variation of a common species, but it has a very unique set of characteristics and *might* be a new species. If we have a specimen in hand, I can sequence the DNA and send the critter itself to a taxonomic expert for further characterization.

2.18.20 C.V.

It was announced a couple of days ago that SD County is the only place in the state with a surplus of rainwater for the season. As a result, even though rain has been sparse since Christmas, things are greening up and blossoms are coming out. The weather has been very sunny and warm. We do have a chance at some rain on Saturday, four days from now. Camera trap has been capturing mostly night-time visitors bunny and rat. It's been a little too cool for the big gopher snake to make his appearance, and I have yet to see the smaller one SM says is underneath the deck. Gophers also are making their mark outside. In-house visitors have included ants lately, and earwigs have gotten in on occasion. Silverfish seem to have disappeared since the house was treated for termites. The milkweed are doing fairly well, but no visitors in the last few weeks, either monarch butterfly nor their caterpillars. I wasn't able to fully participate in Cornell's Backyard Bird Count due to lingering illness -- though tallied what I did see. After about 3 weeks off, I filled the birdfeeder, but the birds have yet to discover it (It's possible they are finding natural food sources at this point). Bees have been drawn to the birdbath lately, I suspect because it has been so dry out, and I do keep it filled regularly. On ground that is hard to grow anything, there continues sprouts of native baccharis, which I protect from the dog with downed branches, on the back slope, and laurel sumac in the front.

Ornithology Field Observation #1 - Morse Park

This birding trip took place on February 17th, 2020. It took place in Morse Park in Monkton, Vermont. I arrived at around 9 am and was greeted by clear skies and sun. The only downfall of this day was the large amount of wind that made the air hurt my face. Morse Park has a large open field with scattered farm homes of local residents. Short trails are lined with deciduous trees, barren of leaves. The main attraction of the park is the large pond that was frozen over with about 10 inches of ice. The open and closed areas provide different types of habitats for birds, which is why I chose this area to go birding.
The first crow I noticed flew overhead of me as I approached a large open area with a frozen over pond. The bird began by circling the perimeter of the pond, but after making it ¼ around the perimeter, it perched on the branch of a leafless tree. The crow flapped its wings up and down as it circled the perimeter of the pond, rarely gliding in flight. The crow seemed to have an elliptical wing shape; rather short and a large amount of spread feathers at the tips. It was extremely windy this day, so the induced drag from the large amount of feathers probably was working to the crows disadvantage. If I was looking to identify this bird in the future, I might be able to tell it was an American crow by the distance it traveled at a high altitude.
The trail that I followed was between a field on the right hand side, and a series of deciduous trees on the left hand side. I saw two blue jays perched on a branch of a tree and observed their wings. They often sat there and shuffled their wings so fast that I could barely see it happen. I believe that they had the “elliptical” wing shape from the way their feathers spread at the tips. I sat and watched them for about ten minutes before they flew away. The bird spread its wings out on the upstroke and seemed to then bring them into the side of its belly on the downstroke. As it approached another branch, it glided and then perched. If I was looking to identify this bird in the future, I might be able to tell it was a blue jay by the unique tucking downstroke.
From what I could decipher, the American crow and the blue jay had the same wing type. However, the American crow had much larger wings than the blue jay. The flight style of the crow was much different than the blue jay as I never saw it gliding through the air. This is probably due to the different habitats I saw the two birds in. The American crow was high up in the air around an open area, while the blue jay was much closer to me and traveled a short distance between trees.

Обновление массива данных iNaturalist в GBIF задерживается

Дорогие друзья!

Обновление массива данных iNaturalist в GBIF задерживается, поскольку на форуме развернулась активная дискуссия с участием топ-менеджеров GBIF и iNaturalist о смене подхода к лицензированию наблюдений. Подробности здесь:

В любом случае, если вы еще не копались в настройках профиля в личном кабинете, то вы можете легко установить открытую лицензию (CC0, CC-BY или CC-BY-NC), а затем подтвердить смену лицензии для всех своих загруженных ранее наблюдений. В этом случае все ваши данные, достигшие исследовательского уровня гарантированно попадут в GBIF, строго сохраняя при этом ваше авторство (если вы, конечно, расшифровали свой ник и добавили в профиле настоящее имя на латинице).

GBIF (Global Biodiversity Information Facility, - это глобальная система, объединяющая в единой точке доступа свыше 50 тысяч баз данных о биоразнообразии. iNaturalist является вторым по объемам источником данных о природе России, уступая только Гербарию МГУ.

Проект "Флора России" обладает исключительно высокой долей свободных наблюдений - почти 81% данных экспортируются в GBIF (в мире доля свободных лицензий не превышает 60%). Всего три топ-наблюдателя проекта из 40 не используют свободные лицензии. Напомню, что именно из GBIF мы будем автоматически экспортировать данные для "Атласа флоры России", поскольку в этом случае мы гарантированно получаем только разрешенные для внешнего использования данные в стандартизированном виде.

Biodiversidad de Artrópodos Argentinos, vol. 2 - FILISTATIDAE

Martín J. RAMÍREZ - Cristian J. GRISMADO

Filistatidae es un grupo pequeño y homogéneode arañas cribeladas y sedentarias con distribu-ción cosmopolita. Se han descripto en todo elmundo 16 géneros y 109 especies, de los cualescuatro géneros y doce especies son conocidas dela Argentina. Las dos subfamilias actualmente re-conocidas, Filistatinae y Prithinae, están represen-tadas en la Argentina. Los filistátidos se recono-cen por la avanzada posición de las hileras y eltubérculo anal, el cefalotórax aplanado y acumi-nado con ocho ojos en un promontorio, el cribelodividido y por detalles de las fúsulas de las hile-ras. Algunos caracteres morfológicos y compor-tamentales sugieren que los filistátidos tienen unaposición crucial entre las araneomorfas basales,y la elucidación de sus parentescos filogenéticoses un dilema muy interesante.

О наблюдениях.

За свое недолгое пребывание на сайте я заметил, что многие наблюдатели стремятся показать одну (в лучшем случае 2) фотографии наблюдаемого объекта, исходя (из логики) что загружать надо только самое лучшее с точки зрения художественной экспозиции фото (самое резкое, красочное и тд.). При этом очевидно, что в большинстве случаев автор должен иметь гораздо больше снимков объекта, чем выкладывает сюда, потому что редко кто делает один "выстрел" и идет дальше. И вот здесь хотелось бы порекомендовать не скупиться на фотографии и показывать как можно больше самого объекта, ведь иногда на самой лучшей на ваш взгляд фотографии окажутся размыты (например) анальные придатки самца стрекозы, что в некоторых случаях сделает определение объекта невозможным, хотя, казалось бы, все остальное резкое, красочное и радует глаз. Просто поверьте, красота снимка на данном сайте, к сожалению, сильно омрачается невозможностью его точного определения. Поэтому не стесняйтесь загружать и 5 и 10 фотографий в одном наблюдение, особенно если у вас много разных ракурсов. Если фотографируете объект в руках то тем более стремитесь показать объект с разных сторон и в деталях. Есть виды которые хорошо распознаются в любых ракурсах (например, Aeshna cyanea), а есть множество тех где в первую очередь важны детали (рода Lestes, Coenagrion, Sympetrum и т.д.).

Данное обращение скорее к любителям, так как специалисты в своей сфере знают с какой стороны лучше показать объект, а доверие к их изначальной идентификации заведомо высоко.

Всего хорошего и удачи всем) Прикрепляю пример наблюдения в руках.

Outramps CREW Diaries
18th February 2020

"Success comes in a lot of ways, but it doesn't come with money and it doesn't come with fame. It comes from having a meaning in your life, doing what you love and being passionate
about what you do."
Tim Tebow

Our dearly beloved Buchu Bus has moved to pastures new after a long life of distinguished service with the Outramps. She is sadly missed, but she was becoming altogether too unreliable for safety.

Nowadays, we mostly have to take 2 cars and the transport expenses are becoming prohibitive. We currently have 3 students, who join us on a regular basis. If you enjoy the Diaries and feel that our work is worthwhile, please consider a donation to our petrol fund. The email address is
and I will send you the Outramps bank details

Album Tuesday 18th February 2020

For captions or info click on i on the top right-hand side. A good way to go - the slideshow is found at the top of the page on the rt hand side by clicking on the 3 dots. Featured this month -The Boys were in Town, Start-Up Meeting 2020, Platberg in the Swartberg, Kat River Circular to Pepsi Pools, Planning Meeting with Ismail , Hartenbos Heuwels with LOT, Out and About in the Southern Cape and some tips for using iNat.
For names and captions of the photos used on this version of the Diaries - see the Album.

For earlier versions of the Outramps CREW Diaries

The Boys were in Town
Watsonias on Cradock Peak:
We wondered what the pink haze was on the top of Cradock Peak and just had to find out. It turned out to be a mass of Watsonias, larger than any display I've ever seen. We were also delighted to see Cyrtanthus elatus (George Lily) around every corner and a real highlight was the discovery of a population of the stunning Geissorhiza outeniquensis (Near Threatened) by Werner.

Other noteworthy trips:
We had a wonderful time on the St. Blaize trail (Cyrtanthus sp.), the Koumashoek Circuit (Erica georgica, Mimetes pauciflorus Vulnerable, Cyrtanthus elatus), Addo (a rooikat kill and lions) and a trip up the eastern ridge of the Swartberg Pass to Oliewenberg (Protea rupicola - Endangered, Protea venusta - Endangered), Leucadendron dregeii Endangered) and the first iNat observation of Erica jugicola - Rare), thanks to Werner.

Start-Up Meeting 2020
A very successful start-up meeting was held at Evie's attractive home "Woodcutters" on Wilderness Heights. It was ably chaired by Jenny Potgieter, as she takes over the reins of the Outramps from the retiring matriarch Di Turner. There was a good turnout and lots of enthusiasm for the work that needs to be done in 2020.

1. The search for Rare and Endangered plants and their monitoring remains our core function
2. Collection of specimens for the Southern Cape Herbarium
3. Seed Collection for MSBP (Millenium Seed Bank Partnership)
4. Engagement with local Municipalities on conservation issues.
5. Recording data on iNaturalist in order to provide a comprehensive checklist of all the flora and fauna that we find wherever we are in South Africa and beyond, with our main focus being the Southern and Western Cape.
6. Training and inspiring youngsters who show an interest in the environment.

We will continue with our weekly SIM field trips and the HAT trips with the Mountain Club. Our young in the Western Cape will be climbing the highest mountains and exploring all over the place. We are hoping that LOT will also be revitalised in 2020. We plan 4 major Overnighters for the year.

Platberg in the Swartberg
It was cool and overcast, which made for pleasant walking on the northern side of the Swartberg. It's a while since we did Platberg and we had an excellent turnout. Nicky and Karol did a short loop and took thousands of photos. Jenny, Rebecca and Di did the whole loop on the northern side and Evie and Dave explored the tops of the hills and found Erica zwartbergensis (Rare) along the way.

Syncarpha ferruginea was a shimmerimg golden colour and Tritoniopsis antholyza was gorgeous in burnt-orange. There were lots of stunning pink Vygies, particularly when we got down on to the Swartberg Pass. We were delighted to find both Leucadendron barkerae and Protea canaliculata, which we haven't seen for ages. The views all along were spectacular.

The find of the day was a small Crassula. Niels Jacobsen of the Southern Cape Herbarium has confirmed that it is a new species in a Group that he is busy revising. Jen had fortunately taken a specimen.

After a lovely day fossicking over a wide area, we returned home very satisfied. The recent rains are already making a big difference to the regeneration of the vegetation on the Swartberg.

Kat River Circular to Pepsi Pools
Budgetary constraints and very high temperatures have combined to keep us local for some of January and early February. The Kat River Circuit is a very pleasant and reasonably cool walk, with the option of a swim at the popular Pepsi Pools higher up the Swart River, before it tumbles down into the Garden Route Dam that is almost full after some good rains. The last part of the walk is a pleasant meander along the northern shore of the Dam. On the downside, this whole area is a striking example of post-fire degradation. Black Wattle is coming up like grass all over the place. This ground is administered by the George Municipality. The size of the problem is daunting and with limited resources, we have no idea of how they are going to tackle it. It would need an army to win this battle.

In between the mess of aliens, some Fynbos is trying to establish itself. Without major intervention, it is doomed to failure. The area immediately around Pepsi Pools is indigenous forest and is holding its own. Just at the entrance to the forest, we saw our only Rare of the day, Erica unicolor subsp. georgensis (Rare).

Joining us for the first time was Nicolette, (she and her husband recently bought Strawberry Hill) and Fred, who is doing his Nature Conservation prac at the Botanical Gardens. We are delighted to welcome them to the ranks of the Outramps and are hoping that they will enjoy the field trips and find them as interesting as we do. The average age of the Outramps is gradually sliding downwards, despite one or two ancients in the ranks.

Putting the Garden Route on the biodiversity map!

City Nature Challenge 2020 on iNat

iNat Training for & Garden Route City Nature Challenge (CNC) 2020 kicks off…
A curious and interactive group came to the formal information and training session for the CNC in Mossel Bay. The members of BotSoc, WESSA, CREW, the Dana Bay and Great Brak River Conservancies; Point of Human Origins scientists; local tour guides who provide for German tourists, birders and the cruise liners visiting Mossel Bay; retirees and the fundraiser/education outreach facilitator for Oceans Research were clearly dead keen to know more and get on board.

The iNaturalist phone App is the ideal tool for the CNC. Training will be given to use the smart phone App to interested
parties in the various Garden Route towns. Follow the Facebook page for updates: or

The CNC Core Committee on the Garden Route are volunteers and still need: Champions for CNC in Hessequa, Kannaland and Oudtshoorn. Anyone wishing to record the biodiversity in their immediate area can take the initiative to coordinate a bioblitz. Posters and information fact sheets are available too. Ask! For further information or requests for iNat training on the handy phone App or an overview of the powerful, versatile computer version, contact Christine:

Planning Meeting with Ismail
It was a steaming, hot day. All thoughts of Flanagans Rock on the northern side of Cradock Peak had fled, with forecast temperatures in the area reaching the upper 30's. So we opted for a shortie on the lower slopes of George Peak. An old Pine plantation provided shade and we had a good view of the unbridled takeover of the area by a host of alien plants. Magnificent Hedychium sp. (Ginger Lily) was in full flower, Solanum mauritianum (Bugweed) was all over the place, Cyathea cooperi (Aussie Invader Fern) was in its element and Sambucus canadensis (Elder) with its showy white flowers against the deep green foliage under the Pine canopy created a cool, green environment in stark contrast to the sizzling heat outside. Little streams coming off the mountain criss-cross the cycle tracks and trails, that are widely used by the locals.

It wasn't exactly the ideal walk to choose for Ismail, who is in charge of CREW in the Western Cape and our dearly-loved boss, but it was short and cool and was followed by the planning meeting at Jen's house. Sumptuous eats, coffee and tea and then we were straight into the meeting. Ismail always brings us a list of target plants for the year and most of them are in impossible places, or haven't been seen for 100 years, or are so inconspicuous that they have largely been ignored. Occasionally he even slots in a couple that are "Presumed Extinct". This time there were about 111 plants on the list. In Cricket parlance that number is called "Nelson" and it is amazing how many wickets fall when the score reaches 111. Are the Outramps going to be bowled out? I wouldn't bet on it. We're a tough old bunch and we've got a whole lot of newies to help us with the search.

It was great to see Ismail again and we are hoping that he was able to find a suitable venue for the CREW Workshop in May. It will be wonderful to have it in our neck of the woods for the very first time.

Hartenbos Heuwels
LOT had their first airing of the year when Gail, Rusell, Wendy and Sally met up at Hartenbos Heuwels for a little perambulation and looksee.

The first plants to get us excited were the delightful Crossyne guttata (I was especially thrilled with these, never having seen the flowers before). They looked like Christmas decorations against the renosterbos. Nearer the dam they were interspersed with showy Boophone disticha in bright pinks. Also in pinks and purples were various Indigofera spp., including the sturdy I. nigromontana.

At the reservoir I was surprised to see a Karoo Scrub Robin, perhaps lured to the coast by the dry conditions. Even more surprising was discovering that there is an indigenous species of Lantana (viz. rugosa) and it's living very happily in the Heuwels.

Rusell collected a bagful of specimens to keep the herbarium volunteers honest and some new species for the area were noted. When a wind with driving rain suddenly picked up, we abruptly called it a day.
LOT will be visiting the Herbertsdale Road on Thursday

News just in - Peter Thompson has just heard that he achieved his MSc Mathematics (cum laude). His thesis was on Protea recognition and he and his supervisor were authors of a paper that will be presented in Colorado in the next couple of weeks. So another one of our young is doing incredible work. We are so proud.

Brian du Preez: A Rare Bud - Returning to Old School Botany in the 21st Century
Date: Friday 21 February 2020
Time: 20:00 - 21:00
Success is usually only achieved through hard work and perseverance, and botany is no different. We have been blessed with a plethora of talented botanical explorers in the Cape Floristic Region over the past few centuries, many of whom were members of the MCSA. Over the past few decades there has however, been a decrease in botanical exploration in the region. Botanists now spend most of their time in the herbarium or office, leaving very few individuals to gather specimens and species data in the field.

As a young botanist, I aspire to return to old school, "boots on the mountain" botany, with the help of some 21st century luxuries. My journey into botany is only 7 years old, but I have been rewarded with some incredible discoveries and some great stories to tell. Please join me for an overview of my journey towards becoming a botanist for the 21st century.

Out and About
We were lucky with the weather. A strong southeaster and cloudy conditions combined to make near-perfect conditions at Bergplaas. Accompanied by our 3 interns, Corné Brink, Rebecca Ryen and Frederick Munro, we set off on the most southerly tracks that look north over the Bergplaas settlement up towards Kleinplaat.

There must have been a stunning display of Watsonias a couple of weeks ago, but only isolated Watsonia fourcadei plants were still flowering. The (Southern Honey Teabush) Cyclopia subternata is growing apace and there has been a huge regeneration of Proteaceae. Schizostephium umbellatum has its first flowers post-burn 2018 and a variety of Ericas were coming into bloom. Notably, we saw Erica glomiflora, discolor, uberiflora and densifolia.

It was a most enjoyable day with our enthusiastic and keen youngsters, but not one single "Rare" was found. This is an unusual occurrence on an Outramps field trip.

Fortunately the "Hot Air" has disappeared for the moment. The temperature in George on Sunday was 42 degrees. Currently it is a glorious 18 degrees.

US and Canadian Turdidae Nests

I spent most of today researching and cross examining photos of US/Canada Turdidae (thrushes) nests. I got the idea of making posts like this from a comment @beartracker made on the neglect of a nest/egg field guide. I will be posting more of these nest/egg identification posts but for now, I'm starting out small and doing it family by family. So here you go!

Bluebirds-- Genus Salia

There are three species of Salia or bluebirds, the Eastern (S. salia), Western (S. mexicana) and Mountain (S. currucoides). They are fairly easy to identify because they are the only thrushes that nest in cavities or birdboxes. I've even seen a few iNat observations of bluebirds even nesting in hollow metal gate polls. Nests are usually made entirely of fine grasses and straw. Eggs are a vivid blue though white clutches can occur.

Since nesting sites, materials, eggs and even nestlings are nearly, if not, identical among the three bluebirds, most sightings will have to be identified by range. Mountain Bluebird eggs are however on the lighter blue of the spectrum, so darker blue eggs in western US are going to be Western Bluebirds. But since Western Bluebird eggs vary from dark blue to white, all other eggs are best left at genus unless a parent was spotted.

Brooding Periods:
Eastern Bluebird -- Feb-Oct -- 3-5 eggs
Western Bluebird -- Apr-Aug -- 2-8 eggs
Mountain Bluebird -- Apr-Sep -- 4-8 eggs

Eastern Bluebird Eggs (blue and white) along with nearly fledged young.

Western Bluebird Eggs and half-grown nestlings.

Mountain Bluebird Eggs (blue and white).

Solitaires Myadestes

There's only one breeding species of solitaire in US and it's the Townsend's Solitaire (M. townsendi) of western US. They are the most unique nesting thrush in North America because they are the only thrush that lays white or cream colored eggs with brown speckling, very similar to Passerellidae or New World Sparrows. They make a nest made of pine needles and grasses on top of a cutbank. Forest roads that cut into the mountain are perfect places to look for a nest. Eggs or young can be found in nests between May and July. Here's a couple photos of eggs in nests.

Varied Thrush Ixoreus naevius

No need to explain what species this is. unfortunately, no photos showing nests or eggs. Varied Thrush nest are hard to come by, since they nest in dense, thick, wet mature forests. They seem to always nest in young pines close to the trunk with the nest contains being moss, mud and grasses. Eggs are blue with black speckling.

Brown Thrushes Catharus and Hylocichla

There are seven species of brown thrushes breeding in North America and in taxonomic order; Veery (C. fuscescens), Gray-cheeked Thrush (C. mimimus), Bicknell's Thrush (C. bucknelli), Swainson's Thrush (C. ustulatus), Hermit Thrush (C. guttatus) and Wood Thrush (H. mustelina). Since eggs and nests are so similar among the species, I think this graph will better illustrate how to identify nest and eggs.

Ground nest with solid blue eggs -- Veery and Hermit Thrush
Ground nest with blue eggs with speckles -- Swainson's Thrush, Hermit Thrush (speckling rare) and Gray-cheeked Thrush (ground nesting rare)
Bush/tree nest with solid blue eggs -- Hermit Thrush (western US only) and Wood Thrush
Bush/tree nest with blue eggs with speckles -- Gray-cheeked Thrush, Bicknell's Thrush, Swainson's Thrush (tree nesting rare) and Hermit Thrush (speckling rare).

When given this information, you can cut down 7 species, though you probably have less in your state/province, to 2 or 3 species. Keep in mind that breeding behavior for Hermit Thrushes differs geographically with western US birds typically nesting in shrubs or trees while eastern US birds are ground nesters.

Veery nest with eggs, including a cowbird egg. Note that cowbirds strongly parasitized Veery and this can be used for identification.

Gray-cheeked Thrush nest with incubating mother.

Bicknell's Thrush nestlings.

Swainson's Thrush eggs.

Hermit Thrush eggs.

Wood Thrush eggs with cowbird egg.

American Robin Turdus migratorius

Robins are fairly easy to identify nests. They are only North America thrush that nests in trees with the exception of the Wood Thrush. They also have a tendency to nest on eaves, buildings and wherever urban. The best way to identify their nest from a Wood Thrush is that robin nests are made of grass and mud while Wood Thrush use grass and leaves.

American Robin eggs and a building nest with nearly fledged young.

And those are the thrushes of North America. Hope this helps!

3 degrees F
NE 6 knot wind
UVM campus and North Prospect Street

From the steps of the AIken building, I observed two Rock Pigeons on the roof of the Davis Center. They took flight and flew as a pair along a curvy flight path. No birds were visible on the main part of campus, though I spotted a Ring-billed Gull flying overhead toward Lake Champlain. Its wing flapping was minimal as it glided by. This flight pattern is made possible by the high aspect ratio of gull wings. High aspect ratio wings have a high wing length to wing width ratio that are most efficient for long and fast flight but not well designed for maneuverability and short bursts of speed.This is because each wing stroke in a high aspect ratio wing will propel a bird a greater distance (less profile drag), but at the cost of quick flaps. This wing shape makes sense for the Ring-billed Gull’s niche, as many Gulls often fly long distances over large water bodies. Indeed, the Ring-billed Gull flew in a fast, direct path with few wing flaps.

There were two hotspots of bird activity along South Prospect Street between Main Street and Redstone Campus. In a yard at the intersection of Robinson Parkway, many birds were seen in bushes and small trees in two yards with bird feeders. The combination of bird feeders and shrubs clearly created a refuge for urban birds in the winter. Black-capped Chickadees, House Sparrows, Blue Jays, and American Goldfinches were vocalizing and moving about. Goldfinches flew in an undulating pattern, characterized by a few rapid wing beats of lift followed by a brief period during which wings were tucked and the bird dropped. Calls of “potato chip” were heard as the finch flew- a very distinctive ID characteristic. This flight pattern differed from that of the House Sparrow, which flew in a direct path with even wingbeats. Theory suggests that undulating flight is most economical for slow flight (Rayner 1985). Also at this stop were two White-breasted Nuthatches, crawling along the trunk of a large maple tree. After observing White-breasted Nuthatches, a few identification traits stood out to me; they like to crawl along trees face-down, and they have black tops to their head that stand in sharp contrast to their white face and breast (see drawing). They are larger than chickadees and do not have a black stripe across their eye as chickadees do. A Tufted-titmouse and a Northern Cardinal were also in the snow beneath a rose bush.

The next hotspot was a fruit-bearing tree near the Redstone campus. Over twenty robins were foraging in the branches and nearby area. A few European starlings were also in the tree and nearby bushes. A few Robins were on the roof of a nearby building, drinking from the edge of a melting snow patch on the roof. The final stop was in the redstone pines, where I heard two woodpeckers drumming but was not able to see them.

Berry Springs Preserve Herps of Texas report, 15Feb2020

After getting almost two inches of rain in the previous week (according to USGS 08105095 Berry Ck at Airport Rd nr Georgetown, TX,, two frog species were seen at Berry Springs Park and Preserve during the monthly monitoring. Rio Grande Leopard Frog (Call Index = 1) was seen at the middle slough springhead and main ponds, and then finally photographed at the ditch in the pecan orchard, where Mike also photographed an American Bullfrog (CI = 0).
There was still no flow to the pond from the middle slough springhead, but again there was more water there than last month. The water level in the main ponds was average.
The monitoring period was 18:20 - 19:50.
Participants were Kathy, Bekki, Mike, Kristin (welcome !), Lynne, and Amy & Mike (and Zelda).
Environmental conditions at the middle slough springhead at sunset:
- Air temperature = 59.9 deg F
- Water temperature = 65.4 deg F
- Sky = mostly cloudy
- Water level = much below average
- Relative humidity = 49 %

Field Journal #2

I went to observe birds around Redstone campus on February 17, 2020 between 4:30pm and 6:00pm. The temperature was between 20 and 25 degrees fahrenheit, and there was a bit of a breeze and snow on the ground. I centered my observations around the small pond and marsh area next to Redstone Lofts, and explored a bit near the Patrick Gym. Overall, I saw many birds during this time - 25 American Robins, 20 European Starlings, 2 Black-capped Chickadees, and upwards of 100 American Crows. The majority of my observations were between 4:30pm and 5:15pm, as it got closer to sunset I observed less and less birds, and by sunset around 5:30pm I saw pretty much no birds.

One behavior I observed ties into the prompt for this week, as all of the American Crows I saw were flying overhead to the southeast. While watching the American Crows I noticed that their flight pattern is very continuous, I rarely saw them stop flapping their wings unless they were much higher in the air. The ones flying higher would sometimes glide for a bit before flapping their wings again. I found this to be very interesting, because I had previously assumed that they would be more inclined to glide rather than flap. The more that I thought about this it made sense because American Crows have elliptical-shaped wings, which are not well adapted for soaring over long distances. When I compared the flight of the American Crows to the flight of the American Robins there were very small differences. The American Robins I observed were not flying long distances, and were much closer to the ground. Their wing shape also seemed elliptical, but they tended to flap their wings a few times and then glide for a second or two with their wings out.

I focused my mini-activity on drawing an American Robin because I have been seeing many of them lately. The features on them that I particularly noticed were their coloring, which is very blocky, the colors do not tend to blend together in their feathers. Obviously I noted the red-ish orange color on the middle of their bodies, which is starkly contrasted with the darker color of their heads and wings. While they were flying, I noticed that they had a lighter block of color in between the red on their stomachs and the black on their tail feathers, which I had never noticed before. I also saw quite a few American Robins on the patches of exposed ground in-between the snow, and they seemed to be foraging around the ground for food.

FJ2: Field Observation: ID and Flight Physiology

Today I visited East Woods UVM Natural Area with my dad. He's here at UVM this week to teach NR 002 students about E.O. Wilson's Half-Earth Project in the hopes of spreading his conservation message/methods across the country. Suffice it to say he was very excited to get out and go birding with me! We spent majority of our morning watching the movement of downy woodpeckers. As I watched, I noticed that downy's like to hitch upward, laterally on, or along tree surfaces using the stiff retrices of their squared tail feathers to support their bodies and provide a spring to aid in momentum. I observed one individual flexing its tail ventrally while it looked for a sturdier grip on the tree/branches it was scurrying on. There were several individuals (some of different species) all in close proximity, and whenever there was a quarrel or the birds were surprised, at least one individual would take off and land on one of the trees a little farther away. Their flight pattern is intermittent, showing the characteristic undulating flight pattern typical of many woodpecker species, alternating quick wingbeats with folding the wings against the body. Compared to a larger woodpecker species, downy's tend to perform more wingbeats between bounds and have bounds of longer duration. The individual I was observing seemed fairly acrobatic, balancing on tiny branches as it foraged. I saw a female and what I believe to be a young juvenile male because he wasn't quite as big as an adult but he had a red tuft of feathers on his head.

Bird flight is the primary mode of locomotion used by most bird species in which birds use their muscles, skeletal structures, and organ systems to assist in propelling them off of the ground. Flight assists birds with feeding, breeding, avoiding predators, and migration. Each facet of this type of motion, including hovering, taking off, and landing, involves many complex movements. As different bird species adapted over millions of years through evolution for specific environments (habitat niches), prey, predators, an other needs, they have developed specializations in their wings, acquiring varied forms of flight. For example, Herring Gulls have high aspect ratio wings, meaning the length of the wing is much greater than the width. This helps them glide which is an important adaptation for a bird that spends most of its life out over open water. Downy woodpeckers have elliptical wings, which allow a high degree of control and maneuverability in confined spaces, minimizing drag and allowing for rapid ascent and descent. This helps downy's avoid predators and efficiently forage in dense forest. If you are not sure what type of bird you are seeing, flight can be a really helpful identifier. Once you see the birds flight pattern and wing shape, you can guess what type of habitat they live in (aka where you would be most likely to find them). This helps narrow down the possible species you would be seeing and brings you much closer to identifying.

I saw a lot of birds this morning and I think this may be because it was earlier in the morning, when many birds especially songbirds tend to be more active. It was also one of the first sunny days in a while and when we walked into the forest, you could feel that there was a lot of energy and commotion. It was still pretty cold (25 degrees) but the sun was reaching through the canopy and felt very warm and nice. The farther we got from the road, the more birds we found. This is partially because it’s hard to hear the birds over the sound of traffic, but also many birds may try to get deeper into the forest to avoid the noise pollution. Another reason I saw these little guys is because they like woodlands, particularly deciduous woods and long streams. This makes East Woods the perfect habitat for them! I really enjoyed this first birding experience however next time I definitely need to bring binoculars, not only to get better identification but also so that I can take better pictures of the birds. I'm excited to go out on more excursions and find different species!

Birding In Charlotte: A Quest For Hawks And A Look At Bird Flight

On February 10th, 2020 I went birding at a new location off of Ferry Rd in Charlotte, VT that I have never been before. My initial intent was to simply scan the nearby fields for signs of Rough-legged Hawk, but once I got out of my car to scan the distant tree lines for birds of prey, I heard a familiar call note flying overhead. Eastern Bluebirds! The temperature was 34 degrees Fahrenheit with a stiff south wind at 5-15 miles per hour. Overcast skies made it difficult to discern any real colors on birds in flight, but once it dropped below the horizon and landed in a nearby sumac tree, I could see the brilliant blue coloration on the bird's head, wings, mantle, and tail, contrasting nicely with a brown breast and white belly. Flying with slow, shallow wing beats, it almost seemed physically unlikely that the bird could remain in the air. Relatively long, pointed wings probably allow for this flight pattern, as they provide the bird's small body with ample lift. It's somewhat erratic bouncing flight makes it hard to believe that they are as nimble and agile as they are in the air. Eastern Bluebirds are birds of open landscapes, especially in during the breeding season when they are primarily aerial insectivores. But in the winter, Eastern Bluebirds flock to road side sumacs and berry producing bushes. Although, long pointed wings with a lot of surface area, may not be the best for zipping through thick undergrowth and weaving in and out of trees in a dense forest, they offer great speed and agility when chasing insects through the open air. While bluebird flight pattern is quite distinctive, it is much easier to make a confident ID when you take into account other aspects of the bird, especially flight calls, which Eastern Bluebirds are known to make.

A scan of the distant tree line resulted in the discovery of 3 Red-tailed Hawks. One of which took off from a treetop just 50 yards away and began circling over head. 3 to 4 powerful wing beats followed by a soar. The bird used it's broad buteo tail as a rudder in the air to tilt it's body toward the center of rotation. I find it hard to imagine that without any direct sunlight or general warming effects from the sun, that there were any thermals for this large adult Red-tail to ride high into the sky, but that's what appeared to be taking place. More likely, the hawks' wings with their high lift primary feathers and high surface area secondaries and covert provided the bird with enough lift to gain altitude without hardly any effort. Red-tailed Hawks, along with the Eastern Bluebird are open land specialists, but in a very different way. While Eastern Bluebirds rely on their wings to be able to sally out from a fence post or branch to catch a passing dragonfly, Red-tailed Hawks rely on their wings for soaring high above open fields and being able to control and hoist larger prey. The flap-flap-glide flight pattern of the Red-tailed Hawk is easily distinguishable from other birds of prey and larger birds in general. The rounded tail that is spread out in flight while the bird glides and the fingered wingtips are characteristics often seen in birds of the Buteo genus along with some vultures and members of the eagle family and even Common Ravens in some instances.

The Rough-legged Hawk is also a member of the Buteo genus along with the Red-tailed Hawk and is known to share an affinity for open landscapes and farmscapes during the winter months. With a flight pattern very similar, if not identical to that of a Red-tailed Hawk, when I saw one of the RTHA take flight for the first time, my heart jumped. "Could it be! My first Chittenden County Rough-legged Hawk since December of 2018?" Right size, right shape, right wing beats, and... nope, totally wrong color pattern and lacking the classic coloration of a RLHA and... a red tail. Rough-legged Hawks breed in the high arctic and parts of Alaska and only winter in the lower 48, so my chances at seeing this amazing species are limited to only the cold winter months from November to Late-March and Early-April (

Yet another bird with a distinctive flight pattern that I saw during this outing were American Goldfinches. These tiny finches are year-round residents in VT and do not need to migrate. Nonetheless, they are quite speedy in the air. With a high arching, undulating flight pattern, American Goldfinches seem to bounce from side to side and up and down when in the air. Similar to a woodpecker flight pattern, they give a few quick beats of their contrasting black wings before folding them against their body in a momentary free fall. In addition to this diagnostic finch/woodpecker flight pattern, American Goldfinches also have a tendency to make high pitched calls in flight. The classic "a-dee-dee-dee.... a-di-du...." flight calls, made with each burst of wingbeats are a great way to ID American Goldfinches by simply seeing them in a distant flyby.

Field Observation: ID and Flight Physiology

The site that I visited for my first field observation journal assignment was Leddy Park in Burlington, Vermont. I arrived at about 10:30 a.m., and for the ninety minutes that I visited, the temperature remained about 25˚. It was also sunny with very little cloud cover or wind. The habitat is actually what drew me to this location the most, and this is because I was able to find a spot that had clear access to Lake Champlain, as well as a relatively large wooded area next to the beach. I thought this would be a great way to see a variety of species, both aquatic and otherwise.
I sat down at an area where I could easily see both the lake and the wooded area. As soon as I arrived at the site, I immediately heard loud pecking into a tree nearby. I scanned the trees until I located where the sound was coming from. A substantial sized bird was standing on the side of a tree, and I knew right away that it was a Woodpecker. However, my excitement only grew when I was able to get a better look at the bird and saw that its beak and neck were longer than that of a Hairy Woodpecker, which was my initial thought since it was too large to be a Downy. I feel quite confident in identifying this bird as a Pileated Woodpecker, based on its size, coloration (black feathers on its back and bright red head), and overall shape. Once I got over the initial excitement at this finding, I continued to search for more species. I then began hearing many songs characteristic of the Black-capped Chickadee and sure enough, the little songbirds were fluttering from tree to tree. Over the delightful “chick-a-dee-dee-dee” sound was the more abrasive caw of the American Crow. I saw one of these birds fly overhead as well, and they are easily identifiable by their size and all-black coloration. Similarly to the American Crow, the sound of the Blue Jay is not always very pleasing. I started to hear their loud jeer sounds from a distance, and it consisted of what sounded like two birds going back and forth. I then tried to ignore these louder birds slightly and focus more on the faint “nasal yank” that I was hearing in the woods. I was able to quickly locate a White-breasted Nuthatch scaling the side of a tree, making the identification much easier for me.
Remaining in the same spot on the edge of the woods, I shifted my focus to the water. I had previously heard some faint sounds coming from the direction of the lake, but as I watched the water, I saw two Mallards flying. I wanted to focus on the flying pattern of these birds because it stuck out the most to me out of all the species I observed. As the birds took off, there was a pair of them (appeared as though there were two females), they remained only a few inches above the water. Their wings moved in rapid up and down motions, and they covered a lot of distance relatively quickly. Since these birds were in the water, it was easy to identify them as Mallards, but the way they fly over the water and move their wings quickly is also helpful in identification. Compared to a species such as the Black-capped Chickadee, the flight pattern of the Mallard is starkly different. The Black-capped Chickadee’s flight consisted of small swooping and fluttering motions between various trees, and they did not cover much distance while I observed them. This makes sense because the Mallards have broad wings that are set toward the back of their body, while Black-capped Chickadees have short wings that are only capable of relatively abrupt and rapid fluttering movements. In terms of habitat, the Mallards were on the lake while the Black-capped Chickadees were in the wooded area.
I felt as though this was a successful birding excursion, especially considering it was my first solo birding experience up here in Vermont. However, I do think I could have seen more species if I had gone out at an earlier time in the morning. The habitat was actually really cool because it had Lake Champlain and forested land, but the trail did not lead very far from the parking lot, which could have been the source of some disturbance for the birds. It was a relatively developed park with a parking lot, ice rink, and even some residential areas, so it would make sense if there were less birds because of those factors. The weather was quite ideal, but of course a lot of birds may not be as active in the colder winter temperatures. In terms of having better luck on the property, I think if I was able to travel further from the more developed areas of the park, I would have been able to hear and see more species.

Shelburne Farms 2/17/2020

Today I went to Shelburne Farms in Shelburne, VT to look for some birds! I was there from about noon to 1:45, and the weather conditions were bright and sunny with some light winds, temperature about 30 degrees.
Immediately when I entered the farm I heard Black-capped Chickadee calls coming from a bush outside of the farm's gift shop. I got closer and counted five individuals hopping/flitting in and around the bush. Occasionally, one would flit down to the ground and would appear to be looking for seeds/other food.
I walked about a quarter mile down the road and took a side trail off to my left that led into some denser tree cover. I immediately heard multiple American Robin calls, and as I moved further into the woods I began to see them gliding from one tree to another, swooping very low to the ground and then increasing their angle of attack to rise sharply up into the next tree, almost like a pendulum swinging.
As I walked further down the trail I heard and observed two White-breasted Nuthatches, one American Crow, and a large group of European Starlings that showed very distinct non-breeding plumage with beautiful speckles. I listened to the Starling's distinctively weird chattering for a while, but couldn't get a great audio recording. I decided to move off-trail into the woods a bit and found myself a place to sit down and try to take some pictures. I was sitting for not even two minutes when something went WHOOSH right by my head, and when I looked up I saw that it was a Pileated Woodpecker that had glided right by me not even five feet away. I watched it maintain that glide for a noticeably longer length of time than the American Robin's did (which makes sense as its wingspan is much larger) and then incline sharply upwards into a tree, take roost, and start pecking. This was a large male with a beautiful bright red crest. I watched him feed for quite a while, taking note of how he moved up and down each tree and between different trees. I got very lucky to have a handful of very different species concentrated in one area, as it made it easy to compare the movements between them. Comparing the similar-yet-different flight patterns of the American Robin and the Pileated Woodpecker really drove home how wing physiology has been adapted for different feeding techniques.

Bird walk 1. February 17 2020

On February 17th, 2020 at 10:00am I left for my 90 Minute bird walk. At the time the temperature was a moderate 24° Fahrenheit with blue sunny skies and little cloud cover. Wind was approximately 5mph out of the north. During this 90 minute walk one thing I particularly keyed in on was the flight pattern of the unidentified hawk. During the 3 minutes I observed this hawk maintained a constant altitude while circling above, while rarely flapping its wings. This entire time, both its wings and tail fan remained fully opened to maximize the amount of lift it experience from gliding. The hawk seemed to have very large rounded wings which would minimize turbulence around wing tips, therefore minimize drag. I hypothesis this style of flight allows hawks to spend a great deal of time in the air searching for prey, while minimizing the amount of energy expended to maintain a constant altitude. This is drastically different from the flight patterns of the Black-capped chickadees which I observed rapidly flapping wings to flitter from branch to branch seemingly to only satisfy curiosity. I speculate rapid movement among black-capped chickadees and other song birds observed, while energetically costly helps them to avoid predation by being able to outmaneuver their large predators in dense tree canopies. While this particular style of flight doesn't seem to be individual to any species of song bird, it would help the observer narrow the possibilities down on a quick glimpse of a bird in flight. Another particularly interesting flight pattern I observed was that of the pileated woodpecker, and hairy woodpecker. Both species of woodpeckers while flying through the woods and open field seemed to have great elevation change on each stroke of their wings followed by a period of tucking and gliding after every elevation gain giving the impression that the woodpeckers were bobbing up and down as they flew. I cannot hypothesize how this style of flight might fit with woodpeckers particular niche, but from what I observed it seems to be practiced only among woodpeckers. Lastly the best observation of flight I had was that of the American crow. From what I saw it appeared the crow was able to extend its wings and fan and glide similar to a hawk but far less efficiently, and also tuck its wings to allow maneuverability among tree tops similar to but not nearly as well as a songbird. Because of this I believe crows flight pattern to be that of a generalist which would allow them stay airborne for long periods of time searching for food, as well as maneuver among treetops to avoid predation. I found studying birds flight patterns to be particularly useful, as it provides a way of quickly identifying a family of birds when rapid movement prevents the observation of markings. While I did see a great number of birds during this observation session, I was not able to closely study bird markings. I believe this was due to my choice of location. the area I was in was mature conifers with a lack of secondary growth. Without secondary growth it seemed birds didn't stray from the tree canopies which prevented me from getting close observations of any species.

Plusieurs étés secs ont affaibli nos forêts

Dans un article publié par La Tribune de Genève aujourd’hui, nos voisins suisses de l’Office fédéral de l’environnement attirent l’attention sur les dégâts causés aux peuplements forestiers par plusieurs étés secs : « Épicéas, hêtres, chênes et sapins blanc ont souffert de la sécheresse. Ces derniers ont même subi des préjudices d’une ampleur inédite… Les peuplements forestiers sont aujourd’hui très affaiblis. Une situation qui favorise la propagation d’agents pathogènes et entraîne le dépérissement d’arbres ». Outre une forte mortalité des hêtres, ils relèvent un nombre élevé de cas d’infestation d’épicéas par le bostryche typographe — que nous avons aussi remarqué en Haute Savoie. Les effets de la sécheresse et ceux des tempêtes, comme celles de juillet 2019, expliquent la forte proportion d’arbres secs ou déracinés que nous avons pu constater cet hiver en forêt, aussi du côté français.
