Black-winged Kite (Elanus caeruleus)
Grey Heron (Ardea cinerea)
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.
