Frigatebird

Frigatebird, any of a family (Fregatidae) of large seabirds with long pointed wings, forked tails, and weak legs. They are superb fliers and spend most of their lives in the air, feeding by snatching fish from the water, picking up baby turtles from the beach, and stealing the food of other birds. They breed in tropical seas. During the mating season, the male has a red throat pouch that may be inflated, for display, to the size of a human head.
