Black-winged Kite (Elanus caeruleus)
Storm Petrel (Hydrobates pelagicus)
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.

CCRarely seen, small petrel. Compact with shorter wings and tail, and blacker plumage than Leach's Storm-Petrel. Squared, unforked tail. White patch on upper tail coverts that reaches down on each side, with more square-cut edges than in Leach's. Also lacks the grey upper wing-band of latter, but shows white stripe on underside of wing. Flight-pattern bat-like with quick fluttering wing-beats and less powerful, and only short, gliding sequences. Sometimes patters with feet on the surface or rests on water. Visits breeding ground at night.
Sound:Heard at breeding ground. Dry, cyclic, rattling and cooing, interrupted by deeper nasal moaning or a higher pitched "kee-ee-kee", with emphasis on second syllable.
