The rock sparrow or rock petronia is a small passerine bird in the sparrow family Passeridae. It is the only member of the genus Petronia. It breeds on barren rocky hills from the Iberian Peninsula and western north Africa across southern Europe and through the Palearctic Siberia and north and central China. It is largely resident in the west of its range, but Asian birds migrate to more southerly areas, or move down the mountains.
Region
Southern Europe, North Africa, and Central Asia (Palearctic)
Typical Environment
The rock sparrow occupies barren rocky hills, cliffs, gorges, and stony plateaus from the Iberian Peninsula and Maghreb across southern Europe to Central Asia and China. It also uses highland pastures, steppe with scattered rocks, and traditional rural areas with stone buildings and walls. Nests are placed in cavities and crevices, including natural rock holes and human structures. Western populations are mostly resident, while eastern and highland birds shift seasonally. It tolerates semi-arid conditions and often forages on open ground near sparse shrubs and grasses.

Social Behavior
Often breeds in loose colonies, placing nests in cavities in cliffs, walls, or buildings, lined with grass and feathers. Pairs are typically monogamous during a season, and both parents feed the young. Outside the breeding season it forms flocks, sometimes mixing with other seedeaters.
Migratory Pattern
Partial migrant
Song Description
The song is a series of clear, slightly metallic chirps and whistles, repeated in simple phrases. Males may deliver song from a perch or during short flight displays. Calls include sharp chips and trills that carry well over rocky terrain.
