Connecticut Warbler
Last Friday after some rain and wind, I was called down to the front of our office building by a coworker who had gone down for a cigarette. She said there was a little bird in distress. As it turned out there were two birds in distress, the one she saw flopping around almost as if it was having seizures being a first-year Cape May Warbler, and another, the stunned Chestnut-Sided Warbler you can see below on the left. I called the Bird Collision Monitors hotline and got their voicemail. After waiting to hear back for about twenty minutes, I thought I could not leave the two birds alone on the sidewalk surrounded by foot traffic, glass and steel, so I took them both to the park-like setting about a block away at 311 South Wacker Drive. You can see them both on the grass below. I sat with them and observed the Cape May was dead, but when I reached for the Chestnut-Sided, it chirped and flew away, so I felt better for having rescued it. When the Bird Collision Monitors did finally call me, they said they had picked up over 200 birds that day. The little bird you see below on the building ledge wasn’t stunned but it was lost, as it flew up from the sidewalk looking for a way out of the buildings. I believe it’s a Least Flycatcher.
There were a lot of birds in the park Friday, so I went back on Monday afternoon with the camera. But not before checking the potted trees in the front of my building, where I found among other more common species, the Connecticut Warbler at the top of this post.

Blackpoll Warbler
There were a lot of Blackpolls but it was difficult to get a decent picture. Although I am thankful for the landscape architects planting lots of locust trees which are great for migrants, the trees are quite tall and I only carry my 300mm lens around with me during the week, so it was a challenge.

Wilson’s Warbler
The Wilson’s Warbler never got low enough for me to capture his trademark skullcap but there’s something so Wilson’s about the shade of yellow. I really think whoever names colors could come up with an entire Warbler Collection. For as many field marks as my brain has memorized, I think I sometimes recognize these birds by the shade of yellow, if there’s good light.

Magnolia Warbler
There’s a familiar phrase, “warbler neck,” which is what you get looking up at these birds in the tall trees.
How nice of this Chestnut-Sided to almost come down to my level.

Then there are the birds that prefer ground level, like the Common Yellowthroat below.

On the other hand I was surprised to find this Pine Warbler in the grass when I later went through my photographs.

It’s been a long time since I’ve gotten close enough to get a good picture of a Black-and-White Warbler and Monday was no exception. This was the best I could do.
American Redstarts come in several color combinations this time of year. The second-year or more adult males are black and orangey-red. The young males are yellow where the red would be, but it’s a warmer yellow than the females. I seem to have captured a bird that is somewhere in between the first and second-year males below the pictures of the older bird, judging from the darker gray on its head and back.
(Click on the pictures just below to see how this male’s plumage is changing.)

The biggest surprise perhaps was to see another Connecticut Warbler. These birds are normally hard to find, and here on the same day I had two within a block of each other.
Suffice it to say that the lure of fall migration is irresistible, especially with nice weather. The birds are taking advantage of the calm skies in this part of the country as well. I have been going back to the park every day this week and as of Tuesday all these birds seem to have left and no new ones have come in. I would like to think they all took off Monday night, navigating well out of the city and continuing their trips to Central and South America.
I’ll have lots more to report if I can manage it. Hope you are having decent weather wherever you are.
