Overview

The striated antthrush, also known as the noble antthrush, is a species of bird in the family Formicariidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru, and is currently assessed as Least Concern by the IUCN.

Identification

• Dark rufescent brown crown and face with white lores, a white streak behind the eye, and a white spot on the side of the neck.
• Underparts are mostly white with a black scalloped effect on the breast and flanks; subspecies C. n. fulvipectus has a rich yellow-ochre breast instead.
• Song consists of a long, accelerating, descending series of hollow, hooting whistles that abruptly shifts to a slower-paced descending series of rising hoots.
