Asthenes humilis
The Streak-throated Canastero (Asthenes humilis) is a petite, cryptic furnariid native to the high Andes, embodying the resilience of avian life in extreme environments. Measuring approximately 15-17 cm (6-6.7 inches) in length and weighing around 15-20 grams, its appearance is subtly camouflaged for its rocky, scrubby habitat. Distinctive field marks include its grayish-brown upperparts, paler underparts with noticeable dark streaks on the throat and breast, a faint pale supercilium, and a r...
This species primarily inhabits high-altitude puna grasslands, rocky slopes, and arid montane scrubland, typically found between 3,000 and 4,800 meters (9,800-15,700 feet) above sea level. It favors areas with dense low vegetation for cover.
Its diet consists almost exclusively of insects and other small invertebrates, which it gleans and probes for among low vegetation, on the ground, and within rock crevices.
The Streak-throated Canastero is a diurnal and rather skulking bird, often observed foraging close to the ground amidst dense clumps of grass or low shrubs. Its primary foraging strategy involves gleaning small invertebrates from vegetation, probing into crevices, and occasionally scratching at l...
The Streak-throated Canastero is a resident species found exclusively in the high Andean regions of South America, spanning across Peru, Bolivia, Chile, and Argentina. Its distribution is generally continuous within this range, inhabiting elevations typically between 3,000 and 4,800 meters (9,800...
Least Concern
- Its common name "Canastero" is Spanish for "basket-maker," a reference to the often elaborate, basket-like nests constructed by many species in its genus. - Despite living in often harsh, cold, high-altitude environments, they are residents year-round and do not undertake significant migrations...
