Planalto Woodcreeper

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."
