It happens every year at about this time: Migrating birds take a day or two off in our neighborhood and hang out in the streets, like a Block Party for the Birds:
Instead of peering up into the leafing-out trees to see warblers, we look down in the gutter:
Instead of beating the bushes to see native sparrows, we wait patiently until they fly out to the pavement:
There were lots warblers and sparrows at our block party, and many more birds were in the streets elsewhere in south Oak Park. Why? We’re guessing it’s because ripening American Elm seeds were knocked to the asphalt by wind and rain, along with many of the bugs that feed on new tree flowers and leaves:
The most abundant warbler species was Yellow-rumped Warbler — the boys counted at least 30 individuals on our block. Palm Warblers were also common in the street — we saw at least a half dozen of them. The best street warbler was an Orange-crowned Warbler, a year bird for us (which would not sit still for a photo). We also saw Pine Warblers and a Northern Waterthrush in trees and on the grass, but not in the street.
The most abundant sparrow on the street was, of course, the House Sparrow, which we hardly count because it’s not native. On our block Chipping Sparrow tied with White-throated Sparrow for the most common native sparrow, but on other blocks White-throated Sparrows won out. Our best street sparrow was a Savannah Sparrow, the first we’ve seen on our block:
We also saw a White-crowned Sparrow right before the rain. Our Block Party for the Birds was cut short by that rain about an hour before sunset. Check back on Tuesday afternoon — we may have more photos. Until then, drive carefully! (Maybe next year we’ll get permission to close the street.)
Back yard birds have been pretty great, too, the last few days. Counting both front and back yard, we recorded 22 species on Sunday and 29 species on Monday. But, that’s another post.
We’re also planning at least one more post about our Mad Dash to Missouri.
Note added Wednesday, April 29, 6:40 a.m.: Tuesday was much colder (mostly upper 40s), and there were few birds on our street for most of the day. Then, as we were preparing to leave for a trip to Columbus Park after school, 7 Yellow-rumped Warblers showed up on the street and nearby sidewalks and even a rooftop.
It seems the pavement party had moved to Columbus Park, although most of the revelers were Palm Warblers. There were several groups of 8 to 10 Palm Warblers on the Park’s asphalt and cinder paths, along with a scattering of Chipping Sparrows and a single Yellow-rumped Warbler.
Note added Wednesday, April 29, 5:30 p.m.: The cold continued today, but I saw at least a few small flocks of birds in the street. One group had a half dozen Yellow-rumped Warblers, a Palm warbler, and a Chipping Sparrow (plus the usual House Sparrows and a Starling).
