Gadfly Petrels
Gadfly petrels form the largest group of tubenosed birds, with about 30 species in the Genera; Pterodroma. ( Pteros = wing and dromas = running, thus 'winged runner'). The name 'gadfly petrel' refers to their impetuous stooping maneuvers in flight, the old name Oestrelata for the genus, derives from the Greek oistrelatos -goaded by a gadfly.
They consist of a diverse assortment of small to medium size species, many of which breed in tropical and sub tropical seas. All have a black bill which is short, deep and heavily hooked. Being oceanic in nature they are rarely seen near land. Their flight is agile, fast and very powerful which is reflected in the name 'gadfly' which these petrels were given by early sailors. When breeding they lay one large egg, usually in a burrow and have long incubation and fledging periods.
