Schwartz's Antthrush

Schwartz's antthrush is 19 to 19.5 cm (7.5 to 7.7 in) long. The sexes are alike. Adults of the nominate subspecies have a slightly rufescent olive-brown crown. They have white lores, a short white streak through their eye, and a whitish streak on the side of their neck. Their upperparts and wings are mostly medium olive-brown with a slightly more rufescent rump. Their tail is dusky brown. Their throat is white with small blackish spots that look like a stripe. Their breast and belly are white with a heavy blackish scallop pattern. Voice: In Venezuela, Schwartz's antthrush has two songs. One is "a remarkably long series of whistled cu notes...without pause, the series gaining slightly in volume, tempo, and pitch as it goes along". The other is "a loud abrupt and descending series of cuu or cuk notes that slow and wind down into a laughlike series of notes that stop abruptly or gradually merge into ".
