On May 19th 2020, between the hours of 6:45 and 12:15 I conducted a bird walk focused on grassland and shrubland species. This walk was conducted on the Ainsworth farm which is an ~800 acre property in South Royalton Vermont on the North side of Vermont Route 110. The property is comprised of a wide variety of habitats including coniferous forest, deciduous, forests, mixed forests, current pastures, overgrown pastures, hay fields, marshes, and corn fields, and riparian. This property was not the assigned location for my bird walk but I chose to substitute it as my location for the day as I know this property well, therefore knew I would be able to locate key areas. I have also in the past noticed a large richness of species present, but never documented species, therefore I saw this as a good opportunity to improve my knowledge about the wildlife community on this property. I feel this was a strong decision as I was able to locate and record 26 species of birds during a short period of time, many of which were target species. During this bird walk I restricted myself to hay fields, overgrown pastures, and current pastures, but I also passed through but didn't focus on deciduous and coniferous forests while traveling between pastures. Over the course of my bird-walk the temperature resided between 55 degrees and 65 degrees Fahrenheit and was mostly sunny with little not no wind. Upon arrival to the property dew was still on the grass but rapidly cleared up.
Bird were very active early in the morning, and vocalizations from different species were often overlapping. As they day progressed bird vocalizations and movement began to slow which I speculate had to do with increased temperature pushing them into denser cover out of open area. The American Crow was easily the most abundant species during my bird walk which I speculated early on would lead to a low abundance of song birds on the property, as i have previously learned crows and ravens often predate on song birds nests. I was surprised to find this was not the case. I believe the high grassland song bird populations was likely due to a large amount of quality habitat which is created by maintained hay fields, overgrown hay fields, and overgrown pasture, as well as a large amount of edge habitat around the perimeters of the hay fields.
One thing which surprised me about bird behavior today was that of the wild turkey. I brought my call with me and was successful at calling in 3 hens, all of which came in silently without responding. Typically in the past I have found hens to be very vocal while coming to a call. I know this is an area of high hunting pressure and speculate this may be due to hunting and predation pressure limiting birds vocal activity. Song bird activity was high today and bird were vocally communicating throughout much of the morning which I believe indicates that wild turkeys lack of vocal communication is stemming from a pressure specifically on their species. Another interested trend I noticed on this property is grassland species spending time in forests, and forest species appearing on grasslands. I suspect this has to do with the fragemented nature of the property leading to species traveling through habitat which they don't typically use to reach other productive habitats on the property. Despite finding a high species richness in this area I feel returning to this area with a greater knowledge of bird songs and a field guide would yield an even higher species richness as I heard many vocalizations today which I was unable to identify due to a lack of experience.
On May 20th 2019 I conducted a morning bird walk to identify forest birds on the ridge which encompasses the Strafford town forest between Van Dyke Road and Taylor Valley road in Strafford Vermont. The temperature over the course of my bird walk was was between 60 and 70 degreed Fahrenheit and the weather was mostly sunny with very few clouds in the sky and relatively little wind. The bird walk I conducted took place between 7:15 AM and 11:45AM. The Strafford town forest and surrounding ridge had a wide variety of habitats including coniferous forest, mixed wood forests, deciduous forests, and early successional habitat near where I entered on the eastern slope, and by the beaver pond on the western portion near Taylor Valley road.
Before entering the field today, I decided it would be most productive for me to spend the first half hour of my allotted field time listening to songs and writing tricks to remember songs by in my notebook, allowing me to refer back to them in the field when I heard an unknown bird song. I found this to be extremely helpful for identifying species which I otherwise would not have been able to identify if I did not take this time before entering the field.
Similar to yesterdays experience in grassland habitat, birds were more active early in the morning and activity began to slow towards mid-morning likely do to the hot temperatures. Based on my previous experiences while being in the woods early in the morning I was surprised to hear a Barred Owl hooting nearly two hours after first light. In the past I have found this species to be active most before first light and shortly thereafter. One thing which surprised me about my birding excursion is the diversity of birds I was able to find on a single mountain. Previous experience while hunting prior to my ornithology class I only noticed common species such as Chickadee's and American Crow's but after learning new species it opens your eyes to the previously looked over diversity of areas I thought to be relatively unproductive. My apologies for failing to take pictures or sound recordings during this bird walk, but my phone wasn't plugged in the night before and was out of battery.
