Asthenes fuliginosa
The White-chinned Thistletail (Asthenes fuliginosa) is a charmingly elusive furnariid, typically measuring 17-19 cm in length, including its relatively long tail, and weighing around 15-20 grams. Its plumage is predominantly sooty gray-brown, lending it a perpetually 'dusty' appearance, highlighted by a distinctive whitish chin patch that serves as a key identification mark. Rufous wing patches are often visible in flight or when the wings are spread, contrasting subtly with the darker body. ...
Found in humid montane forest, cloud forest, elfin forest, and dense scrub, typically at elevations between 2,000 and 3,800 meters in the Andes.
Feeds primarily on small arthropods, including insects and spiders, which it gleans and probes from dense vegetation and leaf litter.

It employs a gleaning and probing foraging strategy, meticulously searching for small arthr...
