Leopold’s Style:

Today, I went for a stroll in one of my favorite areas of New York City’s Central Park: the Evodia Field bird feeders. Under the canopy of Red Oaks lie the swarms of seed-eating birds surrounding an array of almost two dozen feeding stations. Of all its visitors, the Tufted Titmice are most charming, particularly because their antics always interest me. I watch one chow down on a suet cake, one of the most nutritious items in the forest.

Just as he was settling into his feast, something catches his eye. A rival! The two blue-and-white warriors squabble through the air, squeaking and pecking at each other. Finally, they separate, with the rival depleted of stamina. Our titmouse has won the battle, and so returns to his feast.

The Gill

Not far from the feeders lies a small stream colloquially known as the Gill. It starts out with a small waterfall, that widens up into Azalea Pond, then twists and turns farther down, eventually flowing into the Lake. At the mouth, I stood, waiting for some natural event to happen. Suddenly, a flock of yellow jewels flutter down into the stream. These American Goldfinches clearly must’ve gotten a bit dirty with their heads inside the seed feeders. One by one, they dip their bodies into the water, ridding themselves of all the grime that has accumulated throughout the day. They then fly into the bare branches above, spend a few minutes drying off, and then go back to the sources of nourishment they subsist on.

Holland’s Style:

Evodia Field is radically different from the Centennial Thicket. To start, there is no snow on the ground, and it is much warmer. Most of the tree species present in the area are also completely different, and many of them still retain most of their leaves. One species present in both spots is the Northern Red Oak, with several 80-foot giants towering over the relatively low bird feeders.

Speaking of birds, there are a lot more of them than at the Centennial Thicket, with hundreds of individuals of around a dozen species present, compared to the paltry dozen or so birds of four or five species being seen right now. I also saw a migrant species that has long disappeared from the Champlain Valley, two Ruby-Crowned Kinglets. Hardy as they are, these tiny olive birds still migrate, but are more likely to stick around for longer where it is warmer. Every year, a few may even overwinter in the area!

Most notably, Evodia Field is much more altered by humans than the Centennial Thicket. While the thicket only contains one dirt path, Evodia Field contains several fenced-in paved paths. Furthermore, the bird feeders are a major human intervention of the natural cycles. They bring hundreds of birds into a very small area, particularly titmice, sparrows, and finches. It is like an artificial oasis for avian life, and one that I will surely miss once I head back to Vermont.

A bit of a side note is that many finches are coming down from up north! This is known as an irruption, when you get a lot of a species that you typically see very few of during a typical fall/winter. On 19th, I saw several Purple Finches in Central Park, and even a rare Evening Grosbeak!


The leaves have fallen, and so has the snow

Weather: Snowing

Snow cover: 5-6 inches

Birds seen at this spot: Carolina Wren, American Crow, Black-Capped Chickadee

Birds seen nearby: American Robin, American Goldfinch (heard)

This morning the first major snowstorm of the season hit the Centennial Thicket, dropping over half a foot there. This was the second snow event to hit; the first hit on Tuesday and two inches fell. The trees looked very different compared with my last visit almost two weeks ago. The Black Walnuts have now lost all of their leaves, and it seems like the Red Oak only has about half of its leaves left, which are now brown and wilted.


As for birds, a few still seemed to be out during the snowstorm. The resident Carolina Wren scuttled across the path, feeding among the snow-covered shrubs. Chickadees were active as usual in their large feeding flocks. I also found footprints at the edge of the spot (as well as deeper in the woods) that looked to be a few hours old. Based the shape, size, and spacing of the prints, I think they may have been made by a deer.

Meanwhile, I was trudging around covered in a fresh layer of snow!

Everything is Falling Down + Chickadee Banding!

Weather: Mostly sunny, low 40s

Birds seen at this spot: Black-Capped Chickadee,  Blue Jay

Birds seen nearby: Tufted Titmouse, White-Breasted Nuthatch, EASTERN PHOEBE, Common Raven, American Crow, American Robin, Canada Goose

Today I went to visit my phenology site once again. But first, I went out with the Wildlife and Fisheries society (WFS) and Professor Alan Strong to do some Black-Capped Chickadee banding near my spot.

                   ‘Dee and Me!

In total, we banded 9 chickadees, and recaptured two others. I’ll be sure to keep my eye out to see if I can spot any banded birds in Centennial Woods. Other birds in the area included titmice and nuthatches caught in the net, the resident raven flying over constantly calling, and a late Eastern Phoebe flycatching by the pond near the entrance.

One of the nuthatches we caught. These were let go as soon as we freed them.

Most of the trees in the Centennial Thicket seem to have lost virtually all of their leaves. Perhaps the only tree to have nearly all of them is a young Red Oak.

The Red Oak, one of the last leafy trees.

Many of my focal tree species that are visible outside my site, such as Beech and Sugar Maple, still have a lot of leaves, but few of those trees are in my site, likely because the habitat conditions are a bit different deeper into the forest. I better work on how to identify these trees now that most are rapidly losing their leaves!

There is still some greenery on the ground, but little above it.

On a side note, you can observe many changes in the photos I have posted since the blog’s inception, such as trees gradually losing their leaves, as well as the many resident and migratory birds around. On another side note, I have also put together an “event map” in order to showcase some of the things I saw today.
