I went up to the Lake County Fairgrounds in northeastern Illinois this morning. There was a good presence of Thayer's Gulls (5) and Lesser Black-backeds (8). Best of all, birding was from the car which made the 30 mph winds a bit more tolerable.

Still waiting on this season's first Iceland and Glaucous Gull!
Omg!Such beautiful clicks, and these gulls are so cute. How do you differentiate in which one is which, except for the color of the beaks they all look very similar to each other:)
