Common passage migrant. One of the most common of the “Yellow Wagtail” races, often with the commonly occurring Blue-headed race. This race may have an entirely yellow head, superficially similar to the Citrine Wagtail.
In the world
Yellow Wagtail has been split into 2 species: Western Yellow Wagtail, Motacilla flava and Eastern Yellow Wagtail, Motacilla tschutschensis.
It has an extremely large range and in Europe, trends since 1980 show that populations have undergone a moderate decline.
Western Yellow Wagtail breeds in much of temperate Europe and Asia. It is resident in the milder parts of its range, such as western Europe, but northern and eastern populations migrate to Africa and south Asia. This species' systematics and phylogeny is extremely confusing. Literally dozens of subspecies have been described at one time or another, and some 15-20 are currently considered valid depending on which author reviews them.
Indiscriminate shooting, habitat loss and degradation.
