Black-headed Gull
Larus ridibundus

Montrose Harbor, Lincoln Park, Chicago
Cook County, IL
23 February - 15 March+ 2007

This adult Black-headed Gull was first located at Montrose Harbor by John Hockman and Ann Harness on 23 Feb 2007. Kanae Hirabayashi relocated it there on 28 Feb, when I took the first photo appearing below. The bird remained at Montrose Harbor through at least 15 March, when I took the second photo. You can see how the bird is molting in new, black (or dark brown) head feathers.
