The male's upperparts are brown with white, buff, tawny, and black streaks, speckles, and spots. The median wing coverts are white and show as a broad strip on the closed wing. The chin and throat are white or grayish white with a cinnamon wash on the lower throat. The breast is brown with a buff or tawny band separating it from the buffish upper belly and flanks. The breast has blackish brown speckles and the belly and flanks have brown bars and vermiculation. Voice: The Andean potoo's song is "an almost queulous wailing shriek, kwaaaanh, given at intervals of 3-5 seconds". It also produces "a slow, hollow wok wok wok" and "a quieter bu bu bu calls."
