List of birds of North America (Suliformes)

Frigatebirds

Order: Suliformes   Family: Fregatidae

Frigatebirds are large seabirds usually found over tropical oceans. They are large, black or black and white, with long wings and deeply forked tails. The males have colored inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.

Boobies and gannets

Order: Suliformes   Family: Sulidae

The sulids comprise the gannets and boobies. Both groups are medium-large coastal seabirds that plunge-dive for fish.

Cormorants

Order: Suliformes   Family: Phalacrocoracidae

Cormorants are medium-to-large aquatic birds, usually with mainly dark plumage and areas of colored skin on the face. The bill is long, thin and sharply hooked. Their feet are four-toed and webbed, a distinguishing feature among the Pelecaniformes order

Darters

Order: Suliformes   Family: Anhingidae

Darters are cormorant-like water birds with very long necks and long, straight beaks. They are fish eaters which often swim with only their neck above the water.
