Heerman’s Gulls

are often mistaken for jaegers due to their dark, pointed wings and their habit of chasing other birds (particularly pelicans) to steal their prey. They are the only gull species in North America to breed south of the States, but spend winters north of Mexico. Recently, perhaps due to a surge in southern populations thanks to Mexico’s increased protection for the species, a few individuals have attempted to nest in the US on Alcatraz Island.
