Planalto Woodcreeper

The planalto woodcreeper (Dendrocolaptes platyrostris) is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae. It is found in Argentina, Brazil, Paraguay, and Uruguay. == Taxonomy and systematics == The planalto woodcreeper is most closely related to the black-banded woodcreeper (D. picumnus) and Hoffmanns's woodcreeper (D. hoffmannsi) and several authors have suggested that they are conspecific. It has two subspecies, the nominate D. p. platyrostris (Spix, 1824) and D. p. intermedius (Berlepsch, 1883). At least one work has suggested that vocal differences between them warrant their treatment as separate species, but later work does not support that separation. == Description == 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…
