The fact that this place always looks like it may have started on another planet never escapes me, and now I may have some insight into why.
But first I’d like to share a few photos from last Sunday, just as the rain was stopping. I managed to count 40 species, some of which I never saw but recognized by their vocalizations. So spring migration, in spite of whatever weather challenges the birds face, goes on regardless.
My first bird willing to pose was this Spotted Sandpiper. I can’t recall ever seeing one so true to its name. Later I encountered two other common shorebird species, the Killdeer and Solitary Sandpipers below.
Waterfowl was present but not much worthy of a photo except for a solitary Blue-Winged Teal.
The only warblers willing to engage with the camera were Yellow-Rumped and Black-Throated Green Warblers. All the warblers I saw were in the same tree. I had a Blackburnian Warbler which is always a treat, but the poor light just wouldn’t do him justice.
Still here’s the Blackburnian on the left and a Palm Warbler on the right.
And for a blue-gray day, a Blue-Gray Gnatcatcher.
Below is a Brown Thrasher who was singing enthusiastically. I neglected to take my recorder with me but shot the video beneath his picture which recorded some of his song. This is a mimid species, which means he imitates other calls and recites them, singing each call twice. Toward the end of the video a Red-Winged Blackbird sings.
So I have to hand it to the woodpeckers for keeping things lively.
Oops – another Yellow-Rumped Warbler imitating a woodpecker
I was a bit surprised to see a male Belted Kingfisher land and sit still.
And this Red-Tailed Hawk became a bit annoyed with me when I noticed him sitting very still and trying to blend in with the tree.
Close to the end of my outing I found the female Scarlet Tanager below.
But now for the surprise. As I was almost leaving, a cyclist stopped on the bridge where I stood to talk about the Portage. He said he had been visiting this place for 40 years. He didn’t look a day over 52 so I guess he’s been visiting since he was a youngster. Anyway, he told me years ago companies were dumping chemicals here and the water turned numerous bright colors. He also said he had talked to some of the Cook County foresters who were removing trees and they told him they had never seen such strange decay in some of the trunks.
I tried to find some documentation about what he told me but so far I have been unable to find anything specific to the Chicago Portage. I suspect the Environmental Protection Agency postdates the dumping, of course. This explains a lot to me about this strange little oasis in development. It’s sad, but then it’s also encouraging to see how nature rebounds, I guess.
It remains to be seen what the county’s plans are for this place. The cyclist also mentioned something about a commuter train going all the way to Joliet running along I-55 and a transportation hub at Harlem. Just a stone’s throw from the Portage. I can wait.
