Field Ornithology Journal Entry Two 05/19/2020

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.

Descripción

During my Tuesday morning Bird walk, crows were not extremely vocal but had a high number of individuals which were in sight for most of the morning. I estimate there to be 30-40 individual crows on the property, which is a higher concentration than the surrounding area likely to do abundance of agriculture in the valley, providing ample forage for these birds. Although I did not venture down the route 14, I know from previous experience these birds flock in the bottom of the valley after corn in harvested, but it appears they were foraging on grass in the fields along the ridge. One field I observed 13 birds walking through the grass at one time.

I did not visually observe a red-eyed vireo as I was unable to spot it after hearing it. While I was sitting in an overgrown section of abandoned pasture I heard its characteristic song coming from an open section of hardwoods along the southern portion of the pasture. I attempted to find the bird but was unable to.

As I was sitting in a field atop the mountain which is currently used as cow pasture, I heard a singular scarlet tanager singing from an island of brush no more than 100 yards away. As I approached the island I was unable to visual observe the bird as I speculate it saw me coming towards it in the open pasture and flew to cover further away.

I visually observed 2 house wrens during my morning bird walk. I witnessed the first one fly from a bank dominated by honeysuckle and young saplings, across the road in front of me, landing in a honeysuckle bush ~10' in front of me on the trails edge. When I attempted to take a picture the bird flew across the field and out of sight into a group of young pines. The second one I observed was moving amongst the branches of a box elder tree with a group of song birds comprised of common yellowthroats and chestnut-sided warblers. I did not have house Wren songs memorized before entering the field therefore I cannot comment as to the number of house wren vocalizations I heard.

I observed field sparrows in a singular spot on the property. As I was sitting in an abandoned pasture above a current hayfield I watched a pair of field sparrows moving up the honeysuckle along the edge of the field in my direction before departing back into the overgrown pasture. Over the next hour I periodically heard field sparrow vocalizations.
