Curve Billed Thrasher

The Curve-billed Thrasher is generally 25 to 28 cm (10 to 12 inches) long, slender in build with a long tail, and a long, curved, sickle-shaped bill. It is pale grayish-brown above with lighter-colored underparts that are vaguely streaked. The tips of the tail are streaked with white, and the sides of the tail are a darker color than its back. The eye of an adult is usually a vivid orange or red-orange, although immature birds have a yellow eye.
Because of its similar coloration to Bendire's Thrasher, the two birds are easily mistaken for one another. Bendire's Thrasher's shorter and straighter bill and yellow eyes distinguish it from mature Curve-billed Thrashers. However, it is still easy to misidentify a young Curve-billed Thrasher as a Bendire's Thrasher as its beak has not grown to its mature length and curvature, and its eyes are still yellow. Aside from Bendire's Thrasher, the Curve-billed Thrasher can be easily distinguished from other thrasher species in its range as it has a streaked breast, unlike the others' plain breasts.
