Appearance:

Large shearwater with distinct, marked, dark cap and white collar. Blotched belly and underwings. White upper tail-coverts forms a horseshoe mark, but note that Cory's Shearwater may show the same. Dark patch at side of neck. Bill dark. Flight action powerful, with alternating glides and rapid bursts of beats with stiff wings. Seldom soars.

Sound:

Calls at breeding ground a deep, soft, moaning "oooh-aahh" ("surprised or shocked old lady"). Tone fairly clear, and pitch rising and falling.

Appearance:

Underparts almost completely barred. Prominent white edges to primary and secondary coverts. Shorter bill than Common Snipe, with stockier body, but slightly longer wings and legs. Less obvious trailing white edge to secondaries in flight. Corners of tail white (obvious when landing). Usually flies only a short distance and in a straight line after being flushed. Bill held in straighter angle than Snipe in flight.

Sound:

Sometimes utters a faint grunt when flushed, but is generally silent when not lekking. Display call unique: A bubbling, clappering and whistling sequence that accelerates into a crescendo followed by a decrescendo.
