Areale e habitat

The chusquea tapaculo is found only in southern Ecuador and northernmost Peru, from the East Andes and the Chilla Mountains of Ecuador south to Cordillera del Cóndor that straddles the Ecuador-Peru border. As its name implies, the chusquea tapaculo inhabits Chusquea bamboo stands and adjacent undergrowth in humid montane forest. In Ecuador it ranges in elevation from 2,250 to 3,350 m (7,380 to 10,990 ft) but in Peru only to 2,900 m (9,500 ft)

Comportamento

Very little is known about the chusquea tapaculo's diet except that it appears to be mostly insects. Nothing has been published about its foraging behavior.<p>The chusquea tapacolo's nest is a ball of moss lined with fine fibers and placed in a natural cavity in an earthen bank. The only two clutches described each had two eggs. At one nest both adults incubated the eggs. Though year round nesting has been suggested, most breeding in far southeastern Ecuador was between August and December.<p>The male chusquea tapaculo's song is a series of 10 to 12 notes that fall in pitch and then level off [1]. What appears to be an excited call is this [2].
