The white wagtail is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in much of Europe and Asia and parts of North Africa. It has a toehold in Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In Ireland and Great Britain, the darker subspecies, the pied wagtail predominates.
