This is the Continental form of the preceding species, which passes through the country every year on migration and occasionally stays to breed. In habits it is precisely similar to its congener the Pied Wagtail. It may be distinguished by its rather lighter colour, and in summer it retains the light grey back but assumes the black chin.

The females, however, of our own species frequently do not assume a black back, so that the colour of the back when seen in the field will not be sufficient to identify this species. When it can be closely compared it may always be recognised by the clearer grey of the back and pure grey upper tail coverts. In the Pied Wagtail the mantle has a greenish tinge, and the proximal tail coverts are nearly black. Length 7·5 in.; wing 3·5 in.
