Rock Sparrow
Petronia petronia
石雀
Introduction
A small passerine bird in the sparrow family Passeridae. It is the only species in the genus Petronia. The species breeds on barren rocky hills from Madeira and the Canary Islands east through the Iberian Peninsula and western North Africa, across southern Europe and through southwestern and central Asia to Mongolia and the north and west of China. It is resident in the west of its range, but some Asian birds may migrate to more southerly areas or move to lower altitudes in mountains in winter. The species is characterized by a diagnostic yellow throat patch, present in both sexes, and has a loud wheezy song.
Description
This species measures 15–17 cm (5.9–6.7 in) in length, making it slightly larger than a house sparrow. It has a conspicuously larger, more conical bill. The head features a strong whitish supercilium and a weaker crown stripe. The upperparts show a patterned brown coloration on the back and wings, while the underparts are streaked. The most diagnostic feature is a yellow throat spot, which is often difficult to see in the field. The plumage is largely monochromatic earth tones, with the distinctive yellow patch on the upper breast providing stark contrast. This carotenoid-based yellow patch is present in both sexes.
Identification
This species is most readily identified by its larger size compared to the house sparrow and its distinctly larger, more conical bill. The strong whitish supercilium and yellow throat patch are key field marks, though the throat spot can be difficult to observe. The patterned brown back and wings combined with streaked underparts help distinguish it from similar species.
Distribution & Habitat
The species breeds across a wide range from the Atlantic islands of Madeira and the Canary Islands, through the Iberian Peninsula and western North Africa, across southern Europe, and eastward through southwestern and central Asia to Mongolia and northwestern China. It inhabits barren rocky hills and also occurs in human settlements within suitable habitat. Western populations are resident year-round, while Asian populations may migrate south or to lower altitudes in winter. It is a very rare vagrant north of its normal range, with just a single British record at Cley, Norfolk on 14 June 1981.
Behavior & Ecology
Foraging occurs mainly on the ground. The diet consists of seeds throughout the year and berries in autumn; spring feeding includes invertebrates, particularly caterpillars and grasshoppers, which are also fed to the young. The species nests in crevices in rocks or walls, laying four to five eggs. It exhibits various mating patterns including monogamy and polyandry, though social monogamy predominates. Males and females both prefer mates with larger yellow breast patches. Vocalizations include a loud wheezy song. Parental care varies by region: in alpine colonies females perform most provisioning, while in Asian colonies both parents contribute equally.
