Mayan Antthrush
Formicarius moniliger
The Mayan antthrush is 15 to 19 cm (5.9 to 7.5 in) long and weighs about 56 to 64 g (2.0 to 2.3 oz). The sexes have the same plumage. Adults of the nominate subspecies have a dusky brown crown. They have a small white spot on their lores and bare bluish skin around their eye. Their face from their bill to their eye is black that extends down to include the chin and throat. The sides of their neck are rufous that continues across under the black throat. Their nape, back, rump, and uppertail coverts are brown with a rufescent tinge on the last. Voice: The Mayan antthrush's song "begins with a single introductory whistle followed, after a short pause, by a series of 8–14 whistles at a flat pitch, or alternatively gradually increasing or decreasing in pitch piu...piupiupiupiupiupiupiupiupiu!". There appears to be some regional variation in the song. Both sexes sing, primarily in the morning and late afternoon.
