FJ5 - Ethan Allen Park

On April 8th, 2020 between the times 1800-1930 I went to Ethan Allen Park in the North End of Burlington, Vermont. The weather was mostly cloudy, with a slight northward wind of 7mph. It was 49 degrees Fahrenheit. The surrounding habitat was tall oak, maple, etc. trees and a few red or white pines with not much of an under story. It was very rocky with a large rock cliff on the hill. There is a road on either side of this location and a park in the front. There was a lot of human noise pollution. Mostly people talking loudly on their porches and lots of cars driving by. There were only a few people walking along the trails in the park.

For the first 45 minutes I did not see any birds, but could hear them in the distance. I decided to move to a different location within the park in hopes of better luck.

At my new spot there wasn't a ton of bird activity, but I did see a few. The first bird I saw was a small bird, quickly flying past me, not giving me any chance of identifying it. Shortly after I saw two American Robins very briefly, they seemed to be just browsing around. American Robins are found year round in this area, so I am assuming they are facultative migrants? If they even migrate? I'm not sure. According to an online source, some American Robins migrate between 310-933 miles. If these Robins did migrate I think they came from the south (Virginia area maybe?) and are arriving in Burlington for the beginning of spring. Maybe they want to claim their territory before other birds start to migrate back?

Next, I heard a flock of Canadian geese and looked up to spot (my best guess) about 15-25 of them. They were flying north following North Ave, towards the islands in Lake Champlain or Canada. The All About Birds website tells me that some geese could be in this area year round, or they could be returning from the south to breed in northern Canada. I assume most Canadian geese are obligate migrants, except the ones that live in an area that do not require migration. I could not find information regarding typical flock size during migration. Since this flock seemed relatively small compared to others I have seen in my life, I am making the assumption that these specific geese were either not migrating or only migrating a short distance. It makes sense to me that geese who migrate do so in larger flocks. I read that Canadian geese typically migrate between 2,000-3,000 miles.

Lastly, I saw two American crows fly over my head. I do not think these birds were migrating since Burlington is within their year round range.

The total miles traveled by the birds I observed today the miles traveled for migration range between 2,310 and 3,933. That is if the birds I saw were actually migrating. Unfortunately, of all the birds I saw, they were close enough to identify but too far away to take an image or audio recording on my phone. That is why my observations do not have media. On an interesting note, I heard a bird behind me that would not stop calling for twenty minutes straight with VERY little time between calls, I was getting slightly annoyed. It wasn't until I stood up to walk to my car that the bird finally stopped calling (of course). This trip wasn't as successful as I was hoping. I'm starting to think I either pick terrible spots or birds know I'm watching them and laugh as they fly away.

FJ4 - Collier County Excursion

On March 25th, 2020 I went on a birding trip for 90 minutes. I was in Naples, Florida and began observations at 5:18pm EST. The weather was partly cloudy, breezy, humid, and the temperature was ~84 degrees Fahrenheit. The surrounding habitat was man-made as I was in a gated community sitting on a bench near one of the many retention ponds. There were a few tall trees (i.e. palm trees), shorter brush bushes, and smaller shrubby bushes. There were many houses around, groomed landscapes, roads, and sidewalks. Human activity was present in every direction of this area.

Sadly, there were not many birds to see during my time outside. I was not able to witness much interaction between birds. The one interaction I saw were between 4 birds of the same species (was not able to identify). These birds seemed to be "chasing" each other around in a playful manner. They were making calls during this time to which I assumed was a sort of "come and get me" call, or some sort of playful communication. Another assumption is that they were foraging in a group and using their calls to signal about food availability.

The bird I spent the most time observing was the Snowy Egret. This bird was by himself on the shore of the retention pond. His (assuming it was male) plumage was all white. I assume the color white is preference due to the scorching sun and the white may deflect some of the heat. When he first landed he stood still in the same spot for about fifteen minutes. I think this was to scope out the area and check for any predators. After this he browsed the edges of the pond to forage for small water animals/insects. His movements were slow and stealthy, but moved quick when chasing something. Since it was close to sunset I believe this birds daily circadian rhythm was influencing the foraging behavior.

The last birds I saw today were two male Red-bellied Woodpecker's. These two birds flew into the same tree but kept distance between them. They moved around the branches "inspecting" different parts of the tree. They did not make any vocalizations. After about twenty minutes these two left the tree and I can only assume followed one another to another tree to investigate.

Overall this was an interesting excursion due to the fact I was watching birds that are native to a state across the country from Vermont. It was interesting to see species similar to ones in Vermont (woodpecker) and ones not found anywhere close to Vermont (Egret). I developed many questions about bird behavior and weather. The local birds here only encounter warm weather, so I wonder how this contrasts with bird behavior up north. If it wasn't for mandatory quarantine I would love to explore the Everglades here in Florida and all the birds that inhabit the area.

Oakledge Park Excursion

On February 17th, between the times of 1500-1630 hours I observed a few birds while sitting at Oakledge Park in South Burlington, Vermont. It was a sunny day with no clouds, around 24 degrees Fahrenheit. I walked into a small wooded corridor that boarders Lake Champlain. I believe there were mostly small hemlock or cedar trees with a few large Oak trees. It was not densely forested with multiple feet between each tree. It was very quiet on this day with only the sounds of the Lake and the few people roaming the area.
The fist pair of birds I observed were two Canadian Geese flying over the water and then off into the distance. They were rapidly flapping their wings with no observable rests between each stroke. Their wings were somewhat long and narrow but also had width. Since these birds migrate they need this shape of wing to enable them to fly long distances, with good speed, at a time.
The second bird I witnessed was an American Crow. I only caught a quick glimpse and was not able to make out wing shape or flight patterns. I confirmed it was this species based off of its distinct call, which was heard periodically throughout the 90 minutes.
Next I was able to hear the song of a Black-capped Chickadee. I didn't hear or see them right away, it wasn't until I had been sitting for a little while. Once I heard the song I was able to spot one of the three total I observed. After a few minutes of searching I was able to locate the other two. They were calling back and forth to one another (or at least it seemed as so). They were hopping around from branch to branch and mostly flew when moving to another tree. I was able to catch the flight of one bird as it soared over my head to another tree. It flapped its wings quickly and then tucked them in to dive downwards then flapped quickly again to gain height. I was not able to see their wing shape due to their small size, my lack of binoculars, and the speed at which they were flying. I would assume they would be short and wide wings since they mostly stay local to one area.
Lastly, towards the middle/end of my excursion I moved up a slight hill in hopes to see more birds on the other side. To my luck I happened to hear a woodpecker pecking at a tree. This was a Downy Woodpecker who seemed to be solo. I didn't witness much flight, apparently these birds can hop greater distances than I was expecting without opening their wings. From what I did see, it flapped its wings in up and down without much rotation. It had medium length wings with wide feathers. To stop abruptly it pushed its wings forward, spreading out all the feathers.
I did not see many birds on this excursion most likely due to the fact that it was a narrow corridor of trees, with water on one side and an open park on the other. It was rather cold this day so it could be possible some birds were less active to stay warm and save energy. To witness more birds next time I will choose and area that has a larger and more dense forest covering.
