Montane Foliage-gleaner
Anabacerthia striaticollis
The montane foliage-gleaner is 16 to 17 cm (6.3 to 6.7 in) long and weighs 22 to 28 g (0.78 to 0.99 oz). It is a medium-sized furnariid with a wedge-shaped bill. The sexes have the same plumage. Adults of the nominate subspecies A. s. striaticollis have a mostly dark brown face with some pale flecks and a wide pale tawny-buff eyering that extends as a streak behind the eye. Their crown, nape, and upper back are dull dark brown with a hint of buff spots. The rest of their back and rump are rich brown and their uppertail coverts are a slightly paler brown. Voice: The montane foliage-gleaner's song and calls appear to vary little across its range. One description is "an accelerating, belaboured series of staccato, high-pitched, ticking, squeaky, dry 'peck' or 'tchik' notes, roughly on same pitch, sometimes descending slightly at end, sometimes ending abruptly". Its call is "a high, squeaky, sharp 'chit' or 'tchik' ", and it also gives a "scratchy rattle".
