This bird was seen on Treasure Island Beach, Gulf of Mexico, central Florida on June 24, 2013. It walked along the beach near Laughing Gulls, Ring-billed Gulls and Royal and Sandwich Terns. What is it?
The second photo is the mystery gull with a Ring-billed Gull and the last photo is the mystery gull with Laughing Gull and Ring-billed Gull. Hopefully, these photos will provide some idea of size comparison. -SLB
