Black-winged Kite (Elanus caeruleus)
Great Shearwater (Ardenna gravis)
Small, stout, unmistakable raptor with pale grey plumage. Strikingly broad wings and short tail. Large, round, owl-like head with black "mascara" and short neck. Underside of wing-tips, and upper median and lesser coverts black. Immature birds often with rusty underparts and white fringes to flight feathers and scapulars. Glides with wings raised high like a harrier. Frequent and skilfull hovering.
Sound:Not very vocal. A soft "Pjuu-harrr". Starting as a mellow, ascending whistle and ending with a harsh screech. Also uttered without the harsh ending, or only a Barn Owl-like screech. Other sounds: rapid series of soft "kekekekekekekekeke" and short whistles.

CCLarge 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.
