Dusky Antbird

The dusky antbird is 13 to 15 cm (5.1 to 5.9 in) long and weighs 15 to 19 g (0.53 to 0.67 oz). Males of the nominate subspecies C. t. tyrannina are mostly slate gray; their wings and tail are darker and their underparts lighter. They have a white patch between their scapulars and narrow white tips on their wing coverts and outer tail feathers. Their posterior underparts have a clay-colored tinge. Females have a tawny-tinged dark olive-gray crown, upperparts, and wings. They have a very small white interscapular patch. Their wing coverts have cinnamon edges. Their tail is dark grayish brown. Voice: The dusky antbird's song varies somewhat among the subspecies. The male's is generally "a series of relatively short notes at even pitch and pace except for lower-pitched initial and terminal notes". Female's song is typically "a series of long notes rising in pitch followed by series of abrupt notes typically remaining at same pitch".
