Anous albivitta: (Grey ternlet) is a seabird belonging to the tern family, Sternidae. It is 25–30 cm long with a wingspan of 46–61 cm and a weight of about 75 grams). The tail is fairly long and notched. The plumage is pale grey, almost white on the head and underparts but darker on the back, tail and wings. The wings have dark tips and a white hind edge and are mainly white underneath. The eye is black and appears largely due to the black patch in front of it. There is a white patch behind the eye. The thin, pointed bill is black and the legs and feet are also black apart from pale yellow webs.
It occurs in subtropical and warm temperate waters of the South Pacific Ocean. The subspecies P. a. albivitta breeds on Lord Howe Island, Norfolk Island, northern New Zealand (particularly the Kermadec Islands) and southern Tonga (on 'Ata and probably 'Eua). P. a. skottsbergii is found on Henderson Island, Easter Island and Sala y Gómez. P. a. imitatrix breeds on the Desventuradas Islands off the coast of Chile. Some specimens have also been found in Australia, Pitcairn Islands, San Ambrosio and San Feliz Islands and Ellice Islands.
It feeds in shallow water, not moving far from the breeding colonies. It gathers in large feeding flocks which can contain thousands of individuals. They feed by hovering over the water and dropping down to pick food from the surface. Plankton forms the bulk of the diet and small fish are also eaten.
Breeding takes place in colonies on rocky islands. The nest site is a sheltered rocky surface or underneath a boulder or clump of vegetation. A single egg is laid. It is whitish with dark markings and is incubated by both parents for about 32 days. The young birds are fed on regurgitated food and fledge after around 35 days. (Wikipedia)
