Habitat: It is found in breeding season in undergrowth along forest edges and in clearings, also treeless boulder-covered slopes and ridges mostly above treeline with creeping juniper and dwarf willow, alpine meadows, dwarf rhododendrons, bamboo, and birch , juniper and barberry scrub above treeline. It is found at 3800–4200 m in India. In non-breeding season it is found in similar habitat and open hillsides with scrub, mostly at lower levels, down to 2400–3800 m.
Food habits: It eats seeds, buds and shoots of alpine and subalpine herbs and shrubs, also some berries. It forages on the ground and in low bushes. It hops and walks on ground and perches in bushes and trees. It is usually tame and approachable. T is found in pairs and in small, loose flocks. In non-breeding season it is often in single-sex flocks of up to 15 or more individuals, comprising mostly males or immature males, and may associate with other finches.
Breeding habits: They breed from Jun to Aug. They are loosely colonial, territorial, with rather small territory size. The nest is a large shallow cup of grass, dry leaves, moss, plant stems, seedpods and animal hair, placed low down in juniper, dwarf willow or thorn bush. They have a clutch of 3–4 eggs.
