Great Frigatebird is a large seabird in the frigatebird family. Major nesting populations are found in the Pacific (including the Galapagos Islands) and Indian Oceans, as well as a population in the South Atlantic.

It is a lightly built, large seabird up to 105cm long with predominantly black plumage. The species exhibits sexual dimorphism; the female is larger than the adult male and has a white throat and breast, and the male's scapular feathers have a purple-green sheen. In the breeding season, the male is able to distend its striking red gular sac. The species feeds on fish taken in flight from the ocean's surface (mostly flying fish), and indulges in kleptoparasitism less frequently than other frigatebirds. They feed in pelagic waters within 80km of their breeding colony or roosting areas.

Shearwaters, which range from 35 to 65cm in length, nest in burrows on offshore islands and coastal hills in the North Atlantic, eastern South Atlantic, the Pacific and throughout the Mediterranean. These birds feed on fish, squid and other marine creatures while searing out at sea. Large flocks of Shearwaters are commonly seen between March and November, scavenging behind trawlers together with other sea birds. The Shearwater has a very particular call, similar to a crying baby.

This bird breeds in colonies on rocky islands and cliffs, using cavities and burrows. They are frequent breeders and their eggs hatch within 53 days. The largest colony in the Maltese Islands is found at Ta' Cenc cliffs while some pairs also breed on Comino as well as on the Fungus Rock at Dwejra Bay, Gozo.
