Field Ornithology Day 5

May 22nd, 2020
Weather: Sunny, 70 degrees Fahrenheit
Charlotte Park and Wildlife Refuge, Charlotte VT

Habitat: Lots of shrubby habitat mixed with oaks, maples and eastern red cedar. Further up the trail the habitat was more shrubby except for some eastern white pines. At the end of the trail there were two adjacent fields separated by shrubs. Both the trails and the fields were muddy and wet.

Field Ornithology Day 4

May 21st, 2020
Weather: Sunny, 65 degrees Fahrenheit
Geprags Community Park, Hinesburg VT

Habitat: a mixture of grasslands, shrubs, and understory trees. The grasslands were also fragmented by powerlines. The Bobolinks I saw flew low above the open field and chased each other. They landed in the grass to feed and their yellow heads blended in with the dandelions. The shrubs were filled with warblers and the forest had an abundance of Wood Thrushes and Ovenbirds.

Field Ornithology Day 3: Forest Birds

May 20thth, 2020
Weather: Sunny (not a cloud in the sky), 60 degrees Fahrenheit
Green Mountain Audubon Center, Huntington VT
Habitat: On the left side of the road (West) was a forested area with many understory trees. There was a mix of coniferous and deciduous vegetation. The ground was scattered with leaves, twigs and downed logs. This area is where I heard the different warblers and thrushes. I also saw my first Scarlet Tanager and my first Red-breasted Nuthatch. On the right side of the road (East) the elevation dropped a little bit. The area was still forested, but there were more patches of open habitat that were close to water. There were some streams, vernal pools, and a body of water that was something between a swamp and a pond. This area is where I saw my first Brown Thrasher. I also saw some of the more general birds in this area, such as Common Grackles and Red-winged Blackbirds.

Field Journal 7: Reproductive Ecology and Evolution

April 20th, 2020
Derway Island Nature Trail
Sunny, 35°F

• 4 Mallards
• 5 Song Sparrows
• 10 Woodpeckers
• 1 Northern Cardinal
• 4 Canada Geese
• 1 Blue Jay
• 11 Black-capped Chickadees
• 1 Double-crested Cormorant
• 1 White-breasted Nuthatch
• 4 Tufted Titmice
• 1 American Goldfinch
• 3 American Robins

Some of the Robins I saw were sitting solo on a branch—usually of a tree with plenty of berries on it. When they were sitting alone, they made no sounds and just observed their surroundings vigilantly. It’s possible that these Robins were sitting on branches that were close to their nests. There were plenty of materials for nests covering the forest floor that they might have been looking around for. Later during my bird walk, I saw a Robin fly with amazing speed in a straight line across the Winooski River. Another Robin joined by its side. It’s possible that this was a pair flying off to their nest. They were flying too close to each other to not have some sort of relationship.

The Woodpeckers were everywhere. I saw a few, but was overwhelmed by the drumming that I heard in all directions. In contrast to the American Robin, Woodpeckers typically nest in cavities of snags. There were many snags throughout the area, but I didn’t see any evidence of nests. I did not want to be too nosy and scare anyone who was trying to set up a place for incubation. The woodpeckers I actually saw with my eyes were in close proximity to one another, but on separate trees. When one flew away, another one usually took its place, suggesting that they respect each other’s personal space but don’t mind sharing resources (at a distance). The frequent drumming I heard suggests that there were hundreds of Woodpeckers throughout the property trying to defend precious territory and/or attempting to find mates. In my opinion, the abundance of snags and diversity of the land suggests that there is a lot of prime territory. This might be why I saw Woodpeckers foraging relatively close to each other and not exhibiting aggressive behavior. It’s hard to say whether they had high fitness because of the plentiful resources. I wonder how they would do in a less ideal habitat.

The Mallards I saw were only in pairs. I didn’t get a great look at them because they flew away every time I got closer. They always landed together in the water after furiously quacking in the air. Their nest was probably on the ground on the other side of the river where there is less human activity. The other side of the river had a lot of marsh vegetation that would hide their nests well. It’s also probably a good place to easily pull pieces of shallow-root vegetation out of the ground without having he female having to leave her nest. I highly suggest this spot to anyone who wants to see a lot of birds and a diversity of great habitat!

Field Journal 5: Migration

Location: Green Mountain Audobon Center in Huntington, VT
Day: 4/7/20, 1:40-3:30pm
Partly cloudy, 53°F, subtle wind

• 1 Winter Wren
• 3 American Robins
• 12 Black-capped Chickadees
• 1 Blue Jay
• 1 Canada Goose (nesting!)
• 1 Red-winged Blackbird

I had never been to the Audobon Center before and yesterday’s beautiful weather seemed like a perfect opportunity to go. When I pulled into the parking lot, I was overwhelmed by the loud calls of Spring Peepers in Beaver Pond. Around the marsh I could hear the songs of Red-winged Blackbirds, one of Vermont’s famous facultative migrants. Red-winged Blackbirds are short-distance migrants who only travel about 800 miles south in the winter. Males arrive early in the spring and females join them later. The females then build their nests in marsh vegetation. The males will sing on high perches to attract females. The other day I saw a male desperately singing on top of a tree. I later saw a female sitting in a lower shrubby area by the water. I couldn’t tell whether she was impressed by his song.
Another facultative migrant species I saw was the American Robin. I started seeing these guys almost two months ago feeding on berries, but yesterday I saw a Robin tussling with a caterpillar—another sure sign of spring! These birds are year-round residents, but some of them are probably also arriving in VT from the southern United States. As the weather warms up in Vermont, American Robins are probably driven by the abundance of worms, caterpillars, and other invertebrates.

As usual, I saw a bunch of Black-capped Chickadees. Some were doing their mating calls in trees where I couldn’t see them, but most of them were hopping around the shrubs and feeding on berries. Staghorn Sumac seems to be a favorite, I just hope they develop the mental capacity to stay away from Common Buckthorn.

Unfortunately, I did not see any obligate migrants. I decided to do some research on the Scarlet Tanager, a bird that apparently dwells in the forest protected by the Audobon Society where I was doing my bird-walk. This bird that travels across the Gulf of Mexico to winter in South America. The individuals who migrate furthest arrive at their breeding grounds later than the ones who migrate further north on the continent. According to Google Earth, a Scarlet Tanager that travels in a straight line from northern Vermont to Ushuaia, Argentina, flies almost 7000 miles. The birds that go further south migrate north in synchronized bursts rather than all at once. They also migrate mostly at night. I wonder what their main orientation method is. They probably move at night to avoid predators because their bright, colorful feathers make them stick out. The American Bird Conservancy calls them “the guardians of the oaks” because they travel through the treetops of tall, deciduous trees (especially oaks).

Field Journal 4: Social Behavior and Phenology

March 24th, 2020
Burlington, VT
34 degrees Fahrenheit and cloudy

I started my walk on Pine Place. I walked up Pine Place, turned right on St. Paul St, and did a loop by walking down Howard St and making my way back to Pine Place via Pine Street. Starting at Pine Place, I saw four Ring-billed Gulls flying above the neighborhood. As the days have gotten longer and warmer, I have seen many more gulls in Burlington. About a month and a half ago I barely saw any. They squawked at each other in the air. Throughout my walk, the other Ring-billed gulls squawked predictably, even if they were flying solo. To me, all gull squawking sounds the same, but I wonder if what the solo bird is communicating is a different message than that of the birds flying together in a group. Total gulls that day = 10.

I saw a male and female Northern Cardinal in the same shrub. They were a respectful distance apart, but they were still definitely communicating. They chirped at each other and the female bobbed her tail. The Cornell Lab of Ornithology website says that males and females are seen in pairs during the breeding season, but that they stay in flocks during the fall and winter. What strikes me most in cardinals is the male’s brilliant red color that is easily visible, even in dense vegetation. According to the Farmer’s Almanac, male cardinals’ red color attracts females, but what puzzles me is the trade-off between being attractive and being vulnerable to predators. How do these birds find balance between breeding success and survival? Total Northern Cardinals = 3.

When I walked down Howard Street, I saw 6 Rock Pigeons perched on a wire above some houses. Some were facing towards the wind and others were facing away from the wind. They were all approximately six inches apart. They were silent and minding their own business. Some of them preened while others seemed to just be hanging out. They all had their feathers puffed out, so I assume it was a bit chilly up there. Total Rock pigeons = 7.

When I walked down Pine St, I made a stop at Myer’s bagels. Behind their parking lot is a pond surrounded by vegetation, so I thought I’d take a look. A group of European Starlings perched together on a large tree. They were also uniformly spaced and called to each other in a variety of different sounds. They would talk for a while and then fly to a different tree. I also noticed that they didn’t appear as bright and speckled as they did a month ago. Does this mean they are getting ready to breed? Total Starlings = 14.

I heard a bunch of Red-winged Blackbirds by the water but I did not see any. They could have been females picking up pieces of aquatic plants to build their nests for the breeding season. Each call was about five seconds apart. The calls were not fast or urgent sounding, so I assume it was just their normal communication. Total Red-winged blackbirds is unknown.

By the water I also briefly saw an American Robin flying above the water. Total Robins = 1.

I made some spishing sounds on my walk but surprisingly did not see any Chickadees or Sparrows.
