Black-capped Foliage-gleaner

The black-capped foliage-gleaner is 16 to 17 cm (6.3 to 6.7 in) long and weighs 17 to 27 g (0.60 to 0.95 oz). The sexes have the same plumage, with a very dramatic facial pattern. Adults have a wide pale buff eyering, a pale buff supercilium that is more orange-rufous to the rear, a blackish-brown band behind the eye, dull buffy rufous lores, and pale buff ear coverts with blackish-brown bands above and below them. Their crown is dark brown with faint spots on the forehead and faint streaks in its center. Voice: The black-capped foliage-gleaners song is "a somewhat musical, whistled, fast, sharply descending trill" described in more detail as a "rapid series of 6-8 very high notes, the 1st 2 lower...the last 2 slightly lower still". Its calls include an "irregular series of squeaky notes, and 'pit-wit' " and a "very high, metallic sounding 'zic' ".
