Leucosticte arctoa
The Asian Rosy Finch (Leucosticte arctoa) is a striking, cold-adapted passerine, a jewel of the high Asian mountains. Measuring 16-19 cm (6.3-7.5 inches) in length with a wingspan of approximately 30-33 cm (12-13 inches) and weighing 30-40 grams, its most distinctive field marks include a slate-grey head and nape, a dark brown body, and extensive rosy-pink coloration on the flanks, belly, rump, and often on the wings and tail coverts, contrasted by a prominent white patch at the base of the p...
This species primarily inhabits alpine tundra, rocky slopes, scree fields, and glacial moraines at very high elevations, typically above the treeline.
Their diet consists primarily of seeds from alpine plants and grasses, supplemented heavily with insects, especially during the breeding season when protein is crucial for chick development. Foraging is predominantly done by gleaning food from the ground among rocks and sparse vegetation.
Asian Rosy Finches are diurnal, spending their days actively foraging and often roosting in sheltered rocky crevices or under ledges at night. They are highly gregarious outside the breeding season, forming large, nomadic flocks that can number in the hundreds, sometimes mixing with other finch s...
The Asian Rosy Finch boasts a vast, disjunct breeding distribution across high mountain ranges of Asia. Its primary breeding grounds span from Eastern Siberia, including Kamchatka and the Kuril Islands, through Mongolia, the Altai Mountains, and the Tian Shan range, extending into parts of China ...
Least Concern
- The Asian Rosy Finch is one of the highest-breeding passerines in parts of its range, often nesting above 4,000 meters (13,000 feet) in the Himalayas or Tian Shan. - They are remarkably cold-hardy, capable of surviving temperatures far below freezing by fluffing their feathers and roosting in s...
