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".

Northern Barred Woodcreeper
Dendrocolaptes sanctithomae
The northern barred woodcreeper is one of the larger members of its subfamily. It is slim, with a long tail, a medium-length straight bill, and (in the male) a shaggy crest. It is 25 to 29 cm (9.8 to 11 in) long. Males weigh 53 to 72 g (1.9 to 2.5 oz) and females 54 to 83 g (1.9 to 2.9 oz). The sexes have the same plumage. Adults of the nominate subspecies D. s. sanctithomae have a mostly cinnamon-brown face with fine barring, a faint rufous supercilium, black lores, and a rich rufescent forehead, crown, and nape. Voice: The northern barred woodcreeper mostly sings at dawn and dusk but also intermittently during the day. The song of the "western" three subspecies is a series of loud whistles that rise at the end. It is variously put in words as "téw-wee, téw-wee, téw-weea", a "slightly nasal pwee-PWEE-PWEE-PWEE-peeeurr", "a penetrating doh-wee, doh-wee, doh-wee, do-wee", and "oowít, oowít, oowít, OOWIT, OOWIT!".
