Amazonian barred woodcreeper

The Amazonian barred woodcreeper is one of the larger members of its subfamily. It is slim, with a long tail, a medium-length straight bill with a slightly hooked tip, and (in the male) a shaggy crest. It is 26 to 28.5 cm (10 to 11 in) long. Males weigh 50 to 73.5 g (1.8 to 2.6 oz) and females 52 to 79 g (1.8 to 2.8 oz). The sexes have the same plumage. Adults of the nominate subspecies D. c. certhia have a mostly brownish face with fine barring, a weak supercilium, and pale lores and auriculars. Their forehead to crown are darkish olive-brown with golden-buff streaks on the crown. Their back and wing coverts are a lighter olive-brown with weak blackish bars. Their flight feathers, rump, and tail are cinnamon-rufous to rufous-chestnut, with dusky tips on the primaries. Their chin and throat are pale gray to dirty white that contrasts with the deep buff to fulvous underparts; the underparts have fine dusky bars. Their underwing is cinnamon-rufous to ochre-yellow. Their iris is reddish to dark brown, their bill dark red to brownish with lighter edges and base of the mandible, and their legs and feet are brown, greenish, gray, olive, or black. Juveniles resemble adults but with less obvious barring, no pale streaks on the crown, and a shorter and darker bill.

Subspecies D. c. juruanus is like the nominate but without the golden streaks on the crown. D. c. radiolatus is more richly colored than the nominate, more cinnamon-brown above and ochraceus-brown below, and with stronger and darker barring on the back and underparts. D. c. concolor has little or no barring, darker plumage, and a redder bill. D. c. ridgwayi is similar to concolor but with more obvious barring. D. c. medius and D. c. retentus are very similar to the nominate but have a duller crown, a pale gray face, and paler underparts with weaker markings.
