With a body length of around 75 cm (30 in), it is the smallest species. The magnificent frigatebird is a large black bird. The altricial chicks are naked on hatching and develop a white down. Fregata magnificens . Magnificent frigatebirds are carnivores (piscivores) and feed mainly on fish, squid, jellyfish, and crustaceans. [48] Field observations in the Mozambique Channel found that great frigatebirds could remain on the wing for up to 12 days while foraging. Magnificent frigatebirds are gregarious but often fly singly. The Magnificent Frigatebird eats mostly fish and squid, but is also a natural predatory threat to hatchling sea turtles on the beach. The study found the birds do sleep, but usually only using one hemisphere of the brain at a time and usually sleep while ascending at higher altitudes. This egg is incubated by both parents for 50 to 60 days. The Fregatidae are a sister group to Suloidea which consists of cormorants, darters, gannets, and boobies. [18], Magnificent frigatebird (Fregata magnificens), The type species of the genus is the Ascension frigatebird (Fregata aquila). [42], As frigatebirds rely on large marine predators such as tuna for their prey, overfishing threatens to significantly impact on food availability and jeopardise whole populations. Chicks showed nodular skin lesions, feather loss and corneal changes, with around half the year's progeny perishing across the colony. [27][28], A cladistic study of the skeletal and bone morphology of the classical Pelecaniformes and relatives found that the frigatebirds formed a clade with Limnofregata. Females are black but have a white breast and lowe… Although the feathers are black, the scapular feathers produce a purple iridescence when they reflect sunlight, in contrast to the male great frigatebird'sgreen sheen. In the breeding season, males have a bright red throat pouch. It is believed that Magnificent frigatebirds are closely related to Pelicans. Noting that the muscle patterns were different among the steganopodes (classical Pelecaniformes), he resolved that there were divergent lineages in the group that should be in separate families, including frigatebirds in their own family Fregatidae. Magnificent frigatebird feeding habits affect their fish prey, especially flying fish (Exocoetidae), as well as some squid and crustaceans. The only other bird known to spend days and nights on the wing is the Common swift. [42] In 2003, a survey of the four colonies of the critically endangered Christmas Island frigatebirds counted 1200 breeding pairs. [44], According to a study in the journal Nature Communication, scientists attached an accelerometer and an electroencephalogram testing device on nine great frigatebirds to measure if they slept during flight. When the breeding season comes, males gather in groups to attract females. [42], Frigatebirds will rob other seabirds such as boobies, particularly the red-footed booby, tropicbirds, shearwaters, petrels, terns, gulls and even ospreys of their catch, using their speed and manoeuvrability to outrun and harass their victims until they regurgitate their stomach contents. The female is slightly larger than the male and has a white breast and belly. The female lays one clear white egg that measures 68 by 47 millimeters (2.7 by 1.9 in) on average.

In The Birds of North America (P. G. Rodewald, editor). [44] The tail and wings give them a distinctive 'W' silhouette in flight. Frigatebirds bathe and clean themselves in flight by flying low and splashing at the water surface before preening and scratching afterwards. [19], Molecular studies have consistently shown that pelicans, the namesake family of the Pelecaniformes, are actually more closely related to herons, ibises and spoonbills, the hamerkop and the shoebill than to the remaining species. [5][6][b] In the Caribbean frigatebirds were called Man-of-War birds by English mariners. Magnificent frigatebirds occur over tropical and subtropical waters off America, between northern Mexico and Ecuador on the Pacific coast and between Florida and southern Brazil along the Atlantic coast. Overfishing, predator introductions on nesting islands, and hurricanes may also reduce nesting success. The upperparts of the female are dark with lighter wing bars. [44], The duration of parental care in frigatebirds is among the longest for birds, rivalled only by the southern ground hornbill and some large accipitrids. The female is brownish black with a rusty brown mantle and chest, and normally lacks any white patches present on the front of female birds of other species. For other uses, see, A family of seabirds found across tropical and subtropical oceans, Living species and infrageneric classification, Du Tertre wrote: "Loyseau que les habitans des Indes appellent, Columbus's journal survives in a version recorded by Bartholomé de las Casas in the 1530s. Genetic testing seems to indicate that the species has fidelity to their site of hatching despite their high mobility. The magnificent frigatebird is a large seabird that lives in the tropics, along both the Pacific and Atlantic coasts of the Americas. The Magnificent frigatebird is also known as the pirate bird or condor of the oceans. [44] Breeding can occur at any time of year, often prompted by commencement of the dry season or plentiful food. They can fly higher than 4,000 meters in freezing conditions.
