Distribution

In Kazakhstan the Citrine Wagtail breeds in some regions of the northern half of republic (Ural, Ishim, Irgi, rivers, Tengiz-Kurgaldzhin depression), and also in the mountains of Eastern and South-Eastern Kazakhstan. On migration occurs almost throughout. The detailed distribution in Kazakhstan please see in the chapter "Races".

Biology

The Citrine Wagtail is common breeding migrant. Inhabits wet meadow with scattered shrubs, hummock marsh and meadows by mountain steams, as on plains and in mountains up to 1700 m in Altai and at 2300-2800 m in Tien Shan. During migration occurs on shores of lakes and in reed beds. Appears in early March to early April in southern areas, and in early April to early May in northern ones and in mountains, in flocks of 10-15 birds, often with Yellow Wagtail. Last migrants recorded in end May. Breeds in separate pairs in loose colonies. Nest is built on the ground under the bush or grass shelter, or in sedge tussocks up to 30 cm from surface water. It made by female mostly, from dry grass and sometimes is lined with hair. Clutches of 4-6 eggs appears end April to early July. Both parents incubate and feed juveniles, which fledge end May to late July. Long breeding period is explained by phenological differences on the plains and in mountains. Autumn migration begins early August. Most birds leave end August to mid September, last birds recorded in end September - mid October.

Subspecies

Motacilla citreola citreola (Pallas, 1776)

    Description. The mantle is darker than on werae, more dark-grey.
    Distribution. Occurs on migration in plains of Kazakhstan.

Motacilla citreola werae (Buturlin, 1907)

    Description. The mantle is lighter, more ashy grey, than on citreola. The size is in average less than on quassatrix. Male wing length 74.2-83.0 (78.9) mm.
    Distribution. Breeds in northern part of Kazakhstan from Ilek river up to foothills of Altai, and also between Altai and Tien Shan. The passage distribution is deficiently explored.

Motacilla citreola quassatrix (Portenko, 1960)

    Description. The mantle color is same on werae; paler than on citreola; on size larger than werae. Male wing length 85.0-92.4 (89.0) mm.
    Distribution. Probably this race nests in Altai on Chernaya Uba valley; on Markakol lake; in Dzhungarskiy Alatau and Tien Shan. During migration occurs in South and South-Eastern Kazakhstan.

Motacilla citreola calcarata (Hodgson, 1836)

    Distribution. Breeds in highlands of Northern and Central Tien Shan (Ketmen and Zailiyskiy Alatau ridges). It is common on breeding in Western Tien Shan (Uzbekistan) not far of Kazakhstan's boundary. On mid August 2003 in upper Maidantal river (Talasskiy Alatau) two broods recorded on altitude 2480-3100 m, and in upper reaches of Kaskasu river on 2600 m the nest was found 16 July of the same year. On migration occurs in foothills of Western Tien Shan at Chokpak Pass, on Sorbulak lake and in Kolshengel.

Анна Ясько: Отсутствие полной черной полосы перед глазом - это признак возраста. Также клюв у сорокопутов к зиме немного светлеет, особенно у основания.
