Black-banded Woodcreeper
Dendrocolaptes picumnus
The black-banded woodcreeper is one of the larger members of its subfamily. It is slim, with a long tail and a medium-length straight bill. It is 24 to 30.5 cm (9.4 to 12 in) long. Males weigh 47 to 89 g (1.7 to 3.1 oz) and females 48 to 98 g (1.7 to 3.5 oz). The sexes have the same plumage. Adults of the nominate subspecies D. p. picumnus have a dusky face and neck with buffy to tawny streaks and a faint supercilium and eyering. Their forehead, crown, and nape are dark brown; the crown and nape have buff to tawny streaks. Voice: The black-banded woodcreeper sings mostly at dawn and dusk, and only rarely during the day. Birds in Amazonia sing "a loud series...of 15–20 rapidly delivered liquid notes, usually on same pitch, sometimes falling away at end, 'kie-ie-ie--…ie-ee-eu-eu-er', 'glü glü glü glü glü' or 'whi-whi-whiwhiwhi'." Those in Mexico sing a "high-pitched, descending chatter".

Planalto Woodcreeper
Dendrocolaptes platyrostris
The planalto woodcreeper is one of the larger members of its subfamily. It is slim, with a long tail and a medium-length straight bill. It is 25 to 27 cm (9.8 to 11 in) long and weighs 43 to 69 g (1.5 to 2.4 oz). The sexes have the same plumage. Adults of the nominate subspecies have a dusky face with bold buffy streaks and a faint supercilium. Their forehead, crown, and nape are black with bold buff streaks on the crown and nape. Their back and rump are olive-brown with thin buff streaks. Their wings, uppertail coverts, and tail are dull chestnut, with dusky tips on the primaries. Voice: The planalto woodcreeper mostly sings at dawn and dusk. The song of the nominate subspecies is a series of "relatively shrill 'whik', 'week' or 'chree' notes" that fade towards the end. That of D. p. intermedius is "a shorter series of 'yourit' or 'urit' notes". Both subspecies make calls that include "rattling, a grunting 'i-i-i', and other 'squirrel-like' grunts."
