Field Identification

15 cm; 20–25 g. Male of “<em>picata</em>” morph resembles O. albonigra, but is smaller, smaller-headed and less glossy, with lower back and upper breast black, paler flight-feathers below; female is like male, but black replaced by darkish brown, underparts dull whitish. Male “<em>opistholeuca</em>” resembles O. leucura, but smaller and smaller-headed, with brownish flight-feathers, slightly more white on lower back ; female like male, but black replaced by sooty-brown, and has warm brown to chestnut ear-coverts. Male “<em>capistrata</em>” best distinguished from extremely similar male O. pleschanka by often purer white crown , narrower terminal tailband with less black on outermost rectrix; non-breeding male has paler flight-feathers below, less white scaling on throat and mantle; female is usually warmer brown above than female O. pleschanka. Juvenile resembles female, but with broader buff wing edges above, vague buffy scaling below.

Systematics History

Occurs as three forms, considered here as morphs—“picata”, “opistholeuca” and “capistrata”—but commonly treated as races (1), and sometimes even as full species; alternatively, the first two together have been considered as one species, and the third as another, an arrangement which is possibly more appropriate. Populations of “capistrata” × “opistholeuca” exist, however, and there are records of hybrid male “capistrata” × “picata” pairing with female “opistholeuca”. The morph “capistrata” has been thought perhaps to represent a hybrid swarm with O. pleschanka, which both sexes closely resemble. Monotypic.

Subspecies

Monotypic.

Distribution

NE & SE Iran, Turkmenistan and extreme S Kazakhstan (2) E to W Tien Shan, Pamirs, N & W Pakistan and Kashmir; non-breeding SW Asia and SE Arabian Peninsula.

Habitat

Inhabits highly weathered low mountains (below c. 700 m) among sand deserts with grass vegetation in N of range (e.g. Kyzyl Kum, Vakhsh Valley); stony outcrops of the arid foothills of Pamir-Alai Mts, and clay canyons formed by dried-up rivers in S parts of Uzbekistan and Tadjikistan. Form “capistrata” is practically absent in Pamir-Alai system above 1500 m, where replaced by the “opistholeuca” populations occupying montane landscapes. On Iranian plateau and in adjoining mountain systems (Zagros, Elburz and Kopet-Dag) “picata” occurs in foothills to 2100–2400 m (occasionally up to 2700m). Breeds at 1800–2400 m in Pakistan. On wintering grounds found in open rocky areas in deserts and sparsely vegetated areas, also in cultivations; brick kilns (both working and abandoned ones) much favoured in alluvial plains of Punjab, in NW India. Territorial in winter, keeping to same small area throughout.

Movement

Migratory. Early autumn migrant in S Pakistan (Sind), arriving early Aug, and departing end Feb. Non-breeding visitor in UAE, Sept–Mar. Vagrant in E Saudi Arabia.

Diet and Foraging

Small insects , notably ants, small beetles, flies and small grasshoppers, also largers insects, e.g. moths; occasionally also fruit of Ficus and berries of Grewia. Caterpillars seen brought to nestlings. Prey pursued very actively on ground , in air and from low rock perch . Seen to pursue large moths, including hawkmoths (Sphingidae), in flight.

Sounds and Vocal Behavior

Song, from prominent vantage (such as rock, telephone wire or rooftop), occasionally in flight, is scratchy and less pleasant than that of O. albonigra and softer than that of O. isabellina, contains low-pitched “chott” calls, whistles, chirrups and trills, with much excellent mimicry; given also in evening in autumn, at start of winter-territory occupation. Young male in Nov heard to give subsong consisting of soft trills, warbles and thin long whistles. Call  a loud “chek-chek” in warning.

Breeding

Mar–Jun in C Asia; Jun–Jul in Afghanistan and third week Mar to Jul in Pakistan; double-brooded. Territory 2–3 ha in NE of range (Kopet-Dag, Badhyz), average 0·5–1 ha (maximum 3 ha) in semi-desert in Kyzyl Kum and S Uzbekistan, average c. 2 ha in Pamir-Alai Mts; same territory can be occupied in successive years by males of different phenotypes. At start of nest-building female brings numerous flat stones to nest-site (one collected stones from bed of a ravine c. 50 m from site, during 8 minutes delivered 18 stones weighing 1 g to 18 g); nest a bulky, flat cup of grass stems, feathers, animal hair and wool, well concealed in hole in rocks, cliff, wall or bank, under flat stone on rocky slope or in burrow; once under a brushwood-and-mud thatch roof, once in mound of silt excavated from well, once in wood stack, once in tree hole. Eggs 4–7, pale blue with sparse reddish-brown speckles; incubation period 12–13 days; nestling period 13–14 days. In study of 20 nests in range occupied by “picata” morph, 95 eggs hatched and mortality of nestlings was 8·2%; of ten nests in range of “capistrata” × “opistholeuca” populations, unhatched eggs found in five nests and comprised 9·4% of total laid; main nest predators are small snakes and foxes, and in one instance a lizard (Khorasan rock agama) was found in a nest where one nestling dead and another dying.
Not globally threatened. Common in C Asia. Commonest and most widespread wheatear in plains of Pakistan in winter; fairly common in NW India in winter. Breeding density up to 15 pairs/km² in almost unvegetated areas in NE of range. Formerly believed to breed in Jordan, but population there now known to be black morph of O. lugens.
