[edit] Identification

Length = 43 cm (17 in); Weight = 375 g

Male: Slaty-black body, white tail base, narrow buff or white terminal band on tail, long, thin hook on bill. Ceres and feet are orange or red, eyes are red.
Female: Browner with buff-streaked underparts
Immature: Similar to female, but legs brownish and eye brown, with more streaking on breast.

[edit] Similar Species

Easily identified by bill in most of its range. The Slender-billed Kite (local near water in forested areas of South America) has a similar bill and resemble the male Snail Kite in plumage, but is shorter-winged and -tailed, has no white rump, crissum or tail-base and yellow eyes. Immature Slender-billed Kite has darker brownish eyes, but three narrow white tail-bands (incl. tip) unlike any plumage of Snail Kite.
