HabitatIn west Palearctic, narrowly limited to highly arid, warm temperate regions with steep broken gorges, gullies, or crags, minimally vegetated. Avoids open areas, grassland, or scrub, especially wooded steppe or vicinity of forests or cultivation. Extensive lowlands are rarely suitable.Food and FeedingMainly seeds, also leaves, buds, and fruit.

Some populations strictly sedentary, in other populations, some birds make short-distance movements. In Sinai, where breeds at 1000-2000 m in S and C areas, many birds remain at 1000-1500 m in mild winters, in cold winters most birds move down to wadis and other low-lying districts.
