IDENTITY: of Bulwers Petrel
Bulwer's petrel is highly pelagic, and rarely found near land (except during the breeding season). Bulwer’s petrel is a small, sooty-brown petrel, about the size of a prion, but with quite a different shape. It has a long, tapering tail and relatively long, narrow, pointed wings held forward at the carpel joint. Lighter-brown edges to the secondary wing coverts form a pale diagonal band across the upper wing, a feature that is more apparent in good light. The tail looks pointed in normal flight, but is wedge-shaped, a feature only seen clearly when the bird banks and spreads its tail. It has a moderate-sized, smooth black bill with pronounced tubular nostrils. The legs are blackish-pink with dark webs the iris is dark brown. The flight of Bulwer’s petrel is rapid, buoyant and erratic, somewhat bat-like, with loose, wristy, wing-beats. Individuals usually fly close to the sea-surface, especially in strong winds, with short bursts of flapping, while twisting from side to side, interspersed with short, fast glides and quick changes in direction.
HABIT AND HABITAT:
This species is marine and higly pelagic, usually being found far from land except during the breeding season. Its diet comprises mainly of fish and squid, with minor proportions of crustaceans and sea-striders, feeding largely at night by surface-seizing. The breeding season begins in April or May, with individuals forming colonies in a wide variety of habitats on offshore islands. Nests can be burrows, crevices, cracks or caves, under debris or vegetation cover
FOOD :
