The Gull-billed Tern are terns with black caps and unusually thick bills– like a gull. This lets them eat more types of prey than other terns that rely on fish. Gull-billed Terns tackle crabs and lizards on the ground, catch flies, and even steal chicks from other birds. They’re found across the coasts of Central and South America and Southeastern US and California. The U.S. Fish and Wildlife Service considers the species a Bird of Conservation Concern due to boating or construction work near their nesting colonies.
