A long-winged, fork-tailed bird of tropical oceans, the Magnificent Frigatebird is an agile flier that snatches food off the surface of the ocean and steals food from other birds. 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 produce a purple iridescence when they reflect 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.
It spends days and nights on the wing, with an average ground speed of 10 km/hour, covering 223±208 km before landing.
Frigatebirds never land on water, and always take their food items in flight.
