The great frigatebird (Fregata minor) 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.
Males have a distinctive red gular pouch, which they inflate during the breeding season to attract females. Their wings are long and pointed and can span up to 2.3 metres (7.5 ft), the largest wing area to body weight ratio of any bird.
