Their wings and tail are deep chestnut with some black and white on the wing coverts. Their throat, breast, and belly are blackish slate and their flanks, vent area, and undertail coverts are brown. Voice: The chestnut-backed antbird's song is "an easily recognized and imitated set of 2–3 whistled notes, 'peh, peeea' or 'peh, phe, peeéa'...paraphrased as 'come...here' or 'come...right...here' ".

Great Antshrike
Taraba major
The great antshrike is a large and distinctive bird, 19 to 20 cm (7.5 to 7.9 in) long and weighing 47.5 to 70 g (1.7 to 2.5 oz). The species exhibits significant sexual dimorphism, though both sexes of all subspecies have a large crest, a red iris, and a heavy black bill with a hook at the end like true shrikes. Adult males of the nominate subspecies T. m. major have a black head with the color extending to below the eye. Their upperparts are mostly black with a usually hidden white patch between the scapulars. Voice: The great antshrike's song is generally "a long, accelerating series of c. 40 notes, 5–14 seconds, usually ending in a snarl", though the more northern and western subspecies tend to sing fewer notes and often omit the snarl.
