Booby and gannets sulidae

Masked BoobiesThe bird family Sulidae comprises one genus (Sula) and nine species - the Gannets and the Boobies.

Distribution / Range

Gannets are distributed throughout all regions, except the Antarctic. They are usually seen in tropical and subtropical oceans.  Boobies, however, occur in  temperate waters.   They generally remain close to the coast, unlike other seabird species that are mostly pelagic (remain over open waters).  Gannets are migratory whereas boobies tend to be sedentary.


These medium to large-sized seabirds have long, narrow, pointed wings and elongated, cone-shaped bills. Their plumages vary from nearly all white to nearly all black, with some highlights on the wings and paler underparts.

They feed by plunge-diving for fish and other prey.
