The 'Magnificent Frigatebird' (''Fregata magnificens'') was sometimes previously known as 'Man O'War', reflecting its rakish lines, speed, and aerial piracy of other
birds.
It is widespread in the tropical
Atlantic, breeding colonially in trees in
Florida, the
Caribbean and
Cape Verde Islands. It also breeds along the
Pacific coast of the
Americas from
Mexico to
Ecuador including the
Galapagos Islands.
It has occurred as a
vagrant on the
Isle of Man in 1998 and in
Denmark and
Spain. A male was found exhausted at
Whitchurch, Shropshire, many miles from the sea, in November 2005. This individual was taken to
Chester Zoo but died a few days later.
The Magnificent Frigatebird is 100 cm (39 inches) long with a 215 cm (85 inch) wingspan. Males are all black with a scarlet throat pouch which is inflated like a balloon in the breeding season. Although the feathers are black, the scapular feathers are iridescent and produce a purple colour when they refract sunlight. Females are black, but have a white breast and lower neck sides, a brown band on the wings and a blue eye ring. 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. However, it lacks a white axillary spur, and juveniles show a distinctive diamond-shaped belly patch.
The Magnificent Frigatebird is silent in flight, but makes various rattling sounds at its nest.
This species feeds mainly on fish, and also attacks other
seabirds to force them to disgorge their meal. Frigatebirds never land on water, and always take their food items in flight.
