Onychostruthus taczanowskii
The White-rumped Snowfinch (Onychostruthus taczanowskii) is a hardy, high-altitude specialist, instantly recognizable by its striking white rump, black primary coverts, and prominent white wing panel, all contrasting with an otherwise drab grey-brown plumage. Males and females share similar coloration, lacking significant sexual dimorphism.

Exclusively found in high-altitude alpine zones, including barren rocky slopes, plateaus, and sparse grasslands above the tree line, typically between 3,000 and 5,500 meters.
Primarily granivorous, feeding on a variety of small seeds from alpine grasses and forbs, supplemented by small insects and their larvae, especially during the breeding season.
White-rumped Snowfinches are primarily diurnal, spending their days actively foraging on the ground, often in small, loose flocks outside the breeding season. They exhibit typical ground-gleaning behavior, meticulously searching for seeds and small invertebrates among rocks and sparse vegetation....
