Clay-colored thrush

The Clay-colored Thrush (Turdus grayi) is a common Middle American bird of the thrush family (Turdidae). It is the national bird of Costa Rica, where it is well known as the yigüirro. It was formerly known as the Clay-colored Robin. In general appearance and habits it resembles other Turdus thrushes such as the American Robin. It is about the same length or slightly smaller: 23-27 cm (9-10.5 in), and weighs 74-76 g (2.6 oz.) on average. The plumage is brownish, somewhat lighter below than above, lightest on the flanks. Birds from humid regions are darker than those from dry regions. The throat is faintly streaked. Immature birds have faint mottling on the back and underparts. The bill is greenish-yellow with a dark base, the legs are pinkish or flesh-colored, and the irises are reddish---all useful identification points.
