Grey Wagtail

The grey wagtail is a slim wagtail about 18–19 centimetres long. The upperparts are grey, with a narrow white supercilium and a broken eye ring, and the yellow vent contrasting with whitish underparts makes it distinctive. It looks somewhat like the yellow wagtail but has the yellow on the underside restricted to the throat and vent. Breeding males have a black throat edged by whitish moustachial stripes. The call is a clear, sharp note and the song consists of trills. (Wikipedia, general species account)

It is widely distributed across the Palearctic, with several well-marked populations breeding in Eurosiberia and migrating to tropical Asia and Africa. The race melanope breeds in eastern Europe and central Asia mainly along the Urals, Tien Shan and Himalayas, and robusta breeds in northeastern Asia from Siberia to Korea and Japan. When breeding it is always associated with running water, though it may use man-made structures near streams. It forages singly or in pairs on meadows and shallow marshes.
