Grey Wagtail
The Grey Wagtail (Motacilla cinerea) is a small member of the wagtail family, Motacillidae. The species is widely distributed, with several populations breeding in Europe and Asia and migrating to tropical regions in Asia and Africa. The Great Wagtail is usually seen on open marshy ground or meadows where it walks solitarily or in pairs along the ground, capturing insects that are disturbed. Like other wagtails, they frequently wag their tail and fly low with undulations and they have a sharp call that is often given in flight.
The Grey Wagtail is widely distributed across the Palearctic region with several well marked populations. The nominate form (includes caspica of Iran, Turkey and the Caucasus) is from western Europe including the British Isles, Scandinavia and Mediterranean region. Race melanope, which is not well separated from the nominate subspecies, is described as the population breeding in eastern Europe and central Asia mainly along the mountain chains of the Urals, Tien Shan and along the Himalayas. They winter in Africa and Asia. Race robusta breeds along the northeastern parts of Asia in Siberia extending to Korea and Japan.
