Magnificent Frigatebird

Fregata magnificens

The male Magnificent Frigatebird has a red gular sac under the chin, which he inflates to attract a female. You can just see the de-inflated sac under the chin of the male in this photo. I think this male is in non-breeding phase.

The female is slightly larger than the male and has a white breast and belly.

Frigatebirds feed by stealing fish from other birds on the wing. They harass the bird causing them to drop a fish, which they swoop upon. Their range is from Mexico to Brazil on both Pacific and Atlantic coasts.

Immature Magnificent Frigatebirds have a white head as well as white on chest and belly. They keep this plumage for four to six years.
