Asthenes pudibunda
The Canyon Canastero (Asthenes pudibunda) is a modestly sized and cryptically plumaged spinetail, typically measuring around 16-18 cm (6.3-7.1 inches) in length and weighing 18-25 grams (0.6-0.9 ounces). Its plumage is predominantly dull brown dorsally, often with a rufous wash on the rump and tail, contrasting with a paler, sometimes faintly streaked, buffy-whitish belly.

This species primarily inhabits arid montane scrub, puna grasslands, and rocky slopes, often found near ravines, canyons, or rock outcrops. It typically occurs at elevations ranging from approximately 2,800 to 4,500 meters (9,200-14,800 feet) above sea level.
The diet of the Canyon Canastero consists primarily of insects, including beetles, ants, and larvae, supplemented by other small terrestrial invertebrates. It forages by gleaning prey from low vegetation, rocky surfaces, and the ground.
Canyon Canasteros are generally diurnal, often observed singly or in pairs, actively foraging among low shrubs, grasses, and rocky crevices. Their foraging strategy involves gleaning insects and other small invertebrates from foliage, bark, and the ground, often moving quickly with short hops and...
