There have been quite a few chipping sparrow fledglings around the park lately. I'm hearing the little guys begging everywhere. I found a Chipping Sparrow nest a couple of days ago with at least 4 young birds in it. It was in one of the small evergreen trees at the top of the tall stairs (NE of lake), but as of today it's empty.
Since my last update, I've also gotten better views of the Cooper's Hawk nest, and I've seen up to 3 juveniles in the nest with the mother.
