okbirder Posted April 22, 2019 Author Share Posted April 22, 2019 We went to Chicago this weekend fo the first time. I went to Montrose Point which was awesome, but being from Oklahoma, I don't get to ID many Gulls. When I used my Merlin Bird ID, the first picture came up Herring Gull, the second a Glaucous Gull, and the third picture a Ring Billed Gull and a Herring Gull. The immature birds make it difficult for me. What do you think? Link to comment Share on other sites More sharing options...
akiley Posted April 22, 2019 Share Posted April 22, 2019 All of them are Herring Gulls of various ages. The first could have some Glaucous genes bit I'd need better photos to analyze that. Dark primaries rule out pure Glaucous. White-headed Herring Gulls aren't that uncommon. Link to comment Share on other sites More sharing options...

I downloaded the iBird Photo Sleuth and tried it out. It is right on with your observation! Link to comment Share on other sites More sharing options...
