The magnificent frigatebird (Fregata magnificens), frigate petrel or man o' war is a seabird of the frigatebird family Fregatidae. With a length of 89–114 centimetres (2 ft 11 in – 3 ft 9 in) and wingspan of 2.17–2.44 m (7 ft 1 in – 8 ft 0 in), it is the largest species of frigatebird. 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. There are also populations on the Galápagos Islands in the Pacific and the Cape Verde islands in the Atlantic. It is one of the fastest birds in the world, flying at speeds of up to 153 kilometres (95 mi) per hour.
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.

GBIF citizen-science records
It is estimated from how often the Magnificent Frigatebird is recorded against all the birds logged in Rio de Janeiro (3,424 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
