About the Mayan Antthrush

The Mayan antthrush (Formicarius moniliger) is a species of bird in the family Formicariidae. It is found in Belize, Guatemala, Honduras, and Mexico. The Mayan antthrush was formally described as a species by the English ornithologist Philip Slater in 1857. It was later treated by many ornithologists as a subspecies of the black-faced antthrush (Formicarius analis), though some retained it as a species due to significant differences in the two taxa's vocalizations. By 2021 major taxonomic systems had adopted the split.

The Mayan antthrush has three subspecies, the nominate F. m. moniliger (Sclater, PL, 1857), F. m. pallidus (Lawrence, 1882), and F. m. intermedius (Ridgway, 1908). 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... Wikipedia →
