Black-headed Nightingale-Thrush
Catharus mexicanus
The black-headed nightingale-thrush is 15 to 16.5 cm (5.9 to 6.5 in) long and weighs about 30 g (1.1 oz). Adult males of the nominate subspecies C. m. mexicanus have a black crown and a dark gray face with a bright orange eye-ring. Their upperparts are olive-brown. Their throat is white with faint dark streaks, their breast and flanks pale grayish brown, and their belly and vent white. Adult females are similar to males but have a browner head and breast. Subspecies C. m. cantator is slightly smaller than the nominate with a much grayer face and throat and an olive wash on the breast. C. m. Voice: The black-headed nightingale-thrush sings mostly at dawn, dusk, and in the afternoon. Its song is "a series of rapid, thin, flute-like but slightly tinny, fuzzy phrases...e.g. dleet-dloo-dlee-dlee". Its calls include a "harsh complaining upslurred mew, rreahr, meahh or dzeeeet", a "hard dry rattle or trill when agitated", a "soft blurred pseeer", a "slow plaintive chowrr", "grrr", and "meww".

Orange-billed Nightingale-Thrush
Catharus aurantiirostris
The orange-billed nightingale-thrush is 15.5 to 17 cm (6.1 to 6.7 in) long and weighs 21 to 32 g (0.74 to 1.1 oz). The sexes have the same plumage. Adults of the nominate subspecies C. a. aurantiirostris are olive-brown with a rufous tinge on their crown, nape, back, rump, wings, and tail. The rufous is strongest on the last three areas. Their face is grayish brown with a thin orange eye-ring. Their throat is whitish that darkens to pale gray on the rest of the underparts. They have a long, strong, orange bill and brownish orange legs and feet. Voice: The orange-billed nightingale thrush usually sings from dense cover. Its song varies among the subspecies. In northern Central America it is "a scratchy warbling series of sharp whistles and buzzes:chit-TSEE!-tah'wert-PEE'tseee-Cheet or TSIP!-Tseee-cheet-tsee'weet". There its calls are "a sharp, high-pitched whistle, tsseeeeeee" and, as a contact call, "a catlike rreeahhhh".
