Rock Sparrow
Petronia petronia · 石雀
Introduction
A small passerine in the sparrow family Passeridae and the only species in the genus Petronia. It breeds on barren rocky hills from Madeira and the Canary Islands east through the Iberian Peninsula, western North Africa, southern Europe, and southwestern and central Asia to Mongolia and northern and western China. Resident in the west of its range; some Asian populations migrate south or to lower altitudes in winter.
Description
Length 15–17 cm (5.9–6.7 in), slightly larger than a house sparrow with a conspicuously larger, more conical bill. Features a strong whitish supercilium, weaker crown stripe, patterned brown back and wings, and streaked underparts. Displays a diagnostic yellow throat spot and a distinctive yellow patch on the upper breast, contrasting with earth-toned plumage. This carotenoid-based trait is present in both sexes.
Identification
Distinguished by a large conical bill, strong whitish supercilium, and a yellow patch on the upper breast. The yellow throat spot is diagnostic but hard to see. Produces a loud wheezy song.
Distribution & Habitat
Breeds on barren rocky hills from Madeira and the Canary Islands across southern Europe, western North Africa, and southwestern and central Asia to Mongolia and northern and western China. Seven subspecies are recognized: P. p. petronia (Madeira, Canary Islands, south Europe to west Turkey), P. p. barbara (northwest Africa), P. p. puteicola (south Turkey to Jordan), P. p. exigua (central Turkey to Caucasus, north Iran, north Iraq), P. p. kirhizica (Caspian Sea to Kyrgyzstan), P. p. intermedia (Iran, north Afghanistan to northwest China), and P. p. brevirostris (Mongolia, south central Siberia, north and central China). Very rare vagrant north of breeding range, with a single record in Great Britain. Also found in human settlements in suitable country.
Behavior & Ecology
Nests in crevices in rocks or walls, laying four to five eggs. Mating patterns include monogamy, sequential polyandry, and simultaneous polyandry, with social monogamy being most common. Both sexes prefer mates with larger yellow patches. Male brood defense and parental investment increase with female ornamentation. In alpine colonies, females perform most provisioning; in Asian colonies, both sexes contribute equally. Larger males feed young at higher rates. Diet consists mainly of seeds year-round, berries in autumn, and invertebrates (particularly caterpillars and grasshoppers) in spring, which are also fed to young. Forages mainly on the ground.
