Rufous-collared Thrush

The rufous-collared thrush is 23 to 25.5 cm (9.1 to 10 in) long; three individuals weighed 70 to 74 g (2.5 to 2.6 oz). The species is sexually dimorphic. Adult males have a mostly black head with a whitish chin and a throat streaked with black and cinnamon-rufous. They have a wide collar of cinnamon-rufous or chestnut-rufous on the nape and sides of the neck that in front extends to include the breast. Their flanks, belly, and undertail coverts are black. Adult females have a pattern similar to the male's but with lighter and duller colors. Their crown is brownish with darker streaks.

Its song is described as "evenly spaced high-pitched warbling whistles and trills...tre'e'e'e'e-chur'e'e'e'e'e'e-We dirt!-Tea'a'a'a-pretty'dirt'pretty'dirt'irt'irt'irt'irt--We'dirt-tseet!-Tea'Tea'ear'ear'ear'ear'ear". Its call is "chut'chut'chut".
