Tawny-winged Woodcreeper

The tawny-winged woodcreeper is 17 to 19 cm (6.7 to 7.5 in) long. Males of the nominate subspecies weigh 34 to 42 g (1.2 to 1.5 oz) and females 29 to 39 g (1.0 to 1.4 oz). The species is a medium-sized member of its genus, with a straight bill, a short tail, and a ruffled nape. The sexes have the same plumage. Adults of the nominate subspecies have a brown head with buffy supercilium and bare gray skin around the eye. Their crown, nape, and back are dark olive-brown and their uppertail coverts and tail are cinnamon-rufous to rufous-chestnut. Voice: The tawny-winged woodcreeper makes a long rattle song described as "whee-whee-whee-whee..." that may last more than a minute. Its calls include "a plaintive 'squirp', 'deyeew', 'cheeuw', and 'tchee-u'." Another rendition of a call is "an emphatic TEAURRR!".
