Magnificent Frigratebird

The Magnificent Frigratebird (Fregata magnificens) is a seabird of the frigatebird family Fregatidae. It is the largest species of frigratebird. It occurs over tropical and subtropical waters off America, between northern Mexico and Peru on the Pacific coast and between Florida and southern Brazil along the Atlantic 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 it 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 harassing other birds to force them to regurgitate their food.
Distribution
The magnificent frigatebird is widespread in the tropical Atlantic, breeding in trees in Florida, the Caribbean and also along the Pacific coast of the Americas from Mexico to Ecuador, including the Galápagos Islands.
It has occurred as a vagrant as far from its normal range as the Isle of Man, Denmark, Spain, England, Nova Scotia, the Magdalen Islands, and British Columbia.
Description
The magnificent frigatebird is the largest species of frigatebird. Males are all-black with a scarlet throat pouch that is inflated like a balloon in the breeding season. Although the feathers are black, the scapular feathers produce a purple iridescence when they reflect sunlight, in contrast to the male great frigatebird's green sheen. Females are black but have a white breast and lower neck sides, a brown band on the wings, and a blue eye-ring that is diagnostic of the female of the species. Immature birds have a white head and underparts.
This species is very similar to the other frigatebirds and is similarly sized to all but the lesser frigatebird. The magnificent frigatebird is silent in flight, but makes various rattling sounds at its nest.
It spends days and nights on the wing, with an average flapping rate before landing. They climb in thermals, to altitudes occasionally and descend to near the sea surface. The only other bird known to spend days and nights on the wing is the common swift.
Behaviour
Feeding
This species feeds on fish, squid, jellyfish and crustaceans. bird diets vary depending on food availability, preferred hunting technique, gender, and age.
It is a kleptoparasite, pecking at other seabirds to force them to disgorge their meals. After forcing the other seabird to regurgitate its meal, the magnificent frigatebird will dive and catch the prey before it hits the surface of the water
