Frigatebird
Frigatebirds are a family of large tropical seabirds in the family Fregatidae.
Frigatebirds are a family of large tropical seabirds in the family Fregatidae. They are known for very long wings, deeply forked tails, aerial soaring, and males’ inflatable red throat pouches during breeding. Five living species are recognised, and they occur across tropical and subtropical oceans.
Taxonomy and species
Frigatebirds belong to the family Fregatidae and are represented by five extant species. They are generally placed in the order Pelecaniformes or Suliformes depending on the classification system used.
Physical characteristics
These birds are large, slender seabirds with long pointed wings, a long hooked bill, and a deeply forked tail. Their body shape gives them one of the highest wing area-to-body mass ratios among birds.
Behaviour and feeding
Frigatebirds spend much of the day in flight, soaring for long periods on wind currents. They feed on fish and other marine animals and may steal food from other seabirds or take prey near the water surface.
Breeding
They nest in colonies, usually on remote tropical islands or coastal mangroves. Males inflate a bright red gular pouch to attract females during the breeding season.
Distribution and conservation
Frigatebirds occur across tropical and subtropical oceans worldwide. Some species have restricted ranges, and conservation status varies from species to species, with at least one listed as critically endangered.
Key facts
- Frigatebirds are a family of seabirds, not a single species.
- They have long, narrow wings and a deeply forked tail adapted for soaring.
- Males of many species have a red throat pouch used in courtship.
- They are found in tropical and subtropical marine regions.
- Breeding usually occurs on remote islands or mangrove coasts.
Frigatebirds are not regular breeding birds in Canada, but rare vagrants have been reported as far north as Nova Scotia.
