Eastern Yellow Wagtail

The eastern yellow wagtail is a slender wagtail 15–16cm long, with the characteristic long, constantly wagging tail of its genus. It was formerly classified as a subspecies of the western yellow wagtail but was split in 2003, when genetic data showed that classification to be paraphyletic. The heads of breeding males come in a variety of colours and patterns depending on subspecies (Wikipedia, general species account).

It breeds in the eastern Palearctic and Alaska and migrates to South Asia and Australia; most migrate to South-east Asia and Australia in winter, though the non-breeding range extends as far west as eastern India and Sri Lanka. It nests in tussocks, laying four to eight speckled eggs (Wikipedia, general species account).
