Magnificent Frigatebird

Fregata magnificens

The magnificent frigatebird (Fregata magnificens) or man o' war is a seabird of the frigatebird family Fregatidae. With a length of 89–114 centimetres and wingspan of 2.17–2.44 m. It is the largest species of frigatebird. It occurs over tropical and subtropical waters off America, between northern Mexico and Perú on the Pacific coast. The magnificent frigatebird is a large, lightly built seabird with brownish-black plumage, long narrow wings and a deeply forked tail. The male has a striking red gular sac which he inflates to attract a mate. The female is slightly larger than the male and has a white breast and belly. Frigatebirds feed on fish taken in flight from the ocean's surface (often flying fish), and sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food. This species feeds mainly on fish, squid, jellyfish and crustaceans. They may also feed on eggs and chicks taken from the nest of other seabirds, as well as turtle hatchlings and carrion from beaches.
