Scaled Woodcreeper
Lepidocolaptes squamatus
The scaled woodcreeper is 19 to 20 cm (7.5 to 7.9 in) long and weighs about 27 g (0.95 oz). It is a medium-sized woodcreeper with a slim, somewhat decurved bill. The sexes have the same plumage. Adults of the nominate subspecies have a dusky face with whitish streaks and a whitish supercilium that is often broken. Their crown is dark brown lightly spotted with buff. Their back is bright reddish brown and their rump, wings, and tail cinnamon-rufous. Their throat is whitish. Their breast and belly are dusky brown with bold, black-edged, whitish streaks. Voice: The song of the scaled woodcreeper's nominate subspecies is a "series of sharp, connected 'pi' notes, slightly rising and slowing down and sharply falling off at end". Its call is "péeir". The song and call of L. s. wagleri are not well known but appear to be similar to those of the nominate.
