Similar Species
Masked Booby, Red-footed Booby, Australian Gannet, Cape Gannet, and Northern Gannet all have some white on the upperside of the wing in plumages where the head is mostly white. Peruvian Booby and white-headed forms of Brown Booby should not overlap in range with Abbott's Booby.
Distribution
They breed on Christmas Island in the eastern Indian Ocean.
Taxonomy
This is a monotypic species[1].
It is one of ten species belonging to the family Sulidae, gannets and boobies. Abbott's Booby is unique amongst the sulids and was recently placed in its own genus (Olson & Warheit 1988, Christidis & Boles 1994). It has some very ancient characters and may have diverged from other sulids prior to the divergence of gannets (Morus) and boobies (Sula). It is unique in its breeding biology and behaviour (Nelson 1971), and in its osteology (Olson & Warheit 1988)(A Dunn and FAR Hill, Environment Australia, September 1997)
Habitat
Near Christmas Island during breeding, seemingly dispersing to nearby water reaching Java.
Behaviour
Breeding
Nesting is high in trees in the rainforest.
Flight
Abbott's Booby is a strong flier, with easy glides and occasional wingbeats.
Diet
Food includes flying fishes and squid.
