Striated Antthrush

The striated antthrush is 22 to 23 cm (8.7 to 9.1 in) long and weighs about 120 to 150 g (4.2 to 5.3 oz). The sexes are alike. Adults of the nominate subspecies have a dark rufescent brown crown. They have white or buff lores and a white streak behind their eye on an otherwise rufescent brown face. They have a white spot on the side of their neck. Their back, rump, and wings are dark rufescent brown to brown. Their tail is dark olive-brown with a black band near the end and thin white tips on the feathers. Their throat is white. Voice: The song of the nominate subspecies and C. n. rubida is "a long, accelerating, descending series of hollow, hooting whistles that abruptly becomes a much slower-paced descending series of rising hoots...poop poop-pu-pu-pu'pu'pu'pu'pupupupupupupupupupu-WOOP WOOP woop woop woop". That of C. n. fulvipectus is much slower and has many fewer notes than the others' song.
