Resident. High Himalayas. From Large-billed, which can appear raven-like, by longer neck, longer and more angled wings with more pronounced fingered primaries, and more markedly wedge-shaped tail. On the ground, further differences are larger appearance, with more rugged and shaggy look, stouter bill with straighter culmen, prominent throat hackles and flatter crown, more extensive nasal bristles (reaching to centre of bill), and wing-tips fall just short of tail (noticeably short on Large-billed). Agile in flight. and can soar and glide well; performs impressive aerobatics, often tumbling, diving with closed wings and rolling on to the back in mid-air. Dry rocky area sabove tree line.
