What do frigate birds eat

Present year-round in southern Florida; in northern Florida and along Gulf Coast, more common in summer. Nesting colonies are widely dispersed among islands and coasts of tropical America and very locally off west Africa , but nonbreeders and immatures are seen far from colonies at all seasons. Small numbers mostly immatures regularly wander inland in southwest in summer. Rarely wanders north along coasts or far inland.

The same climate change-driven threats that put birds at risk will affect other wildlife and people, too. Gathered in groups, males excitedly rattle their slender bills against their inflated bright red throat pouches. Latin: Elanoides forficatus.

Their favorite way to catch a meal is to harass other birds until they spit out their hard-earned catch. Especially during the breeding season, some species focus heavily on just a few types of prey. Frigates also follow fishing vessels and eat the scraps thrown overboard. Human interaction varies from species to species.

Fishermen sometimes kill these birds for fun, or because the birds try to steal fish. Another important threat to these birds is humans hunting their eggs and chicks at their nesting colonies. Because birds nest in large numbers, humans can make huge impacts on population numbers when they destroy nesting colonies.

Feral animals, like cats and rats, also introduced by humans, also kill nesting birds and their young. Natives on some islands in the Pacific Ocean used to capture young birds and tame them as pets.

They even used the pet birds as messengers to deliver letters from one island to another. However, their lifestyle was quite different from most households today. In modern homes, Frigate Birds would not make good pets. It is also illegal to own a Frigate Bird as a pet in most places. In a zoological setting, these birds have needs that are similar to other seabird species.

The frigatebirds swoop down from above to pursue the target, pulling at the bird's wings or tail, in an attempt to force the bird to disgorge and drop its prey items.

If successful, the dropped food item is plucked from the air by one of the agile frigatebirds. Frigatebirds form mixed flocks with other Pelecaniformes for breeding and roosting. They generally forage singly or in small groups of two or three individuals, but may flock over an abundant food source. Frigatebirds are often quiet in flight or when perching. Colonies are often noisy.

Males and females have distinctive vocalizations. Adults elicit twittering, drumming, rattling and bill clattering. Young birds chirp or squeal. Major threats include: habitat degradation, introduced predators, and human disturbance at breeding sites. The evolutionary relationships of frigatids remain unclear. Frigatebirds have been considered related to other totipalmate birds tropicbirds, anhingas, gannets and boobies, pelicans, cormorants and anhingas , which when taken together, form Pelecaniformes.

Frigatebirds have been considered most derived within Pelecaniformes. However, some hierarchies include frigatebirds within Ciconiiformes or Charadriiformes. Morphological, ethological and molecular analyses suggest differing hypotheses of sister group relationships: frigatebirds as sister to a group comprising pelecanids pelicans , sulids boobies and gannets , phalacrocoracids cormorants and anhingas ; frigatebirds as sister to procellariids tubenoses ; frigatebirds as sister to a group consisting of spheniscids penguins , gaviids loons , procellariids petrels, shearwaters, albatrosses.
