Ascension Frigatebird

Fregata aquila

The Ascension Frigatebird, *Fregata aquila*, is a striking and critically endangered seabird endemic to the remote Ascension Island in the South Atlantic. These magnificent aerialists boast a wingspan of up to 2.2 meters (7.2 feet) and a body length of 89-96 cm (35-38 inches), with a body mass typically ranging from 1.2 to 1.5 kg (2.6-3.3 lbs). Males are entirely glossy black, except for a spectacular, inflatable scarlet gular pouch displayed during courtship. Females are larger and distingui...

Habitat

Ascension Frigatebirds are pelagic seabirds, spending most of their lives soaring over the open ocean but requiring offshore, predator-free islands and islets for breeding and roosting.

Diet

Their diet primarily consists of fish (especially flying fish), squid, and sometimes the chicks of other seabirds, often acquired through kleptoparasitism or by surface-skimming.

Behavior

These frigatebirds are largely diurnal, spending countless hours effortlessly gliding high above the ocean currents, only returning to land for roosting and breeding. They are highly specialized foragers, primarily engaging in kleptoparasitism, snatching food directly from other seabirds in mid-a...

Range

The Ascension Frigatebird's breeding range is highly restricted, exclusively occurring on Ascension Island and its satellite islet, Boatswain Bird Island, in the South Atlantic Ocean. Historically, they bred on the main island, but feral cats forced the entire population onto the inaccessible Boa...
