Anabazenops dorsalis
The Bamboo Foliage-gleaner (*Anabazenops dorsalis*) is a striking passerine bird of the ovenbird family (Furnariidae), known for its strong association with dense bamboo thickets in Andean foothill forests. This medium-sized bird measures approximately 18-19 cm (7-7.5 inches) in length. Its most distinctive feature is its rich rufous or chestnut back and rump, contrasting with an olive-brown crown and nape, often exhibiting subtle streaking. It has a prominent pale buffy supercilium above a d...
Found primarily in humid subtropical or tropical moist montane forests, with a near-exclusive preference for dense *Chusquea* bamboo thickets. It typically inhabits elevations between 900 and 2,400 meters.
Feeds almost exclusively on arthropods, including insects and spiders, which it gleans and probes from bamboo foliage and culms. Its specialized foraging technique allows it to extract prey from hidden crevices.
The Bamboo Foliage-gleaner is a diurnal bird, typically observed alone or in pairs, though it occasionally joins mixed-species foraging flocks. Its foraging strategy is highly specialized: it gleans and probes meticulously among dense bamboo culms, leaf sheaths, and curled dead leaves, often hang...
The Bamboo Foliage-gleaner is a resident species with a relatively restricted and disjunct distribution across the humid montane and foothill forests of western South America. Its primary range includes southeastern Peru, specifically in the departments of Cusco and Puno, extending southwards int...
Least Concern
- The Bamboo Foliage-gleaner is an obligate bamboo specialist, meaning its survival is intrinsically tied to dense bamboo thickets. Its presence is a strong indicator of healthy bamboo forest ecosystems. - Its scientific name, *dorsalis*, refers to its distinctive rufous or chestnut-colored back,...
