White Wagtails have white, black and grey markings in all plumages. The sexes can be distinguished by the colouring on their heads: males have black markings on the back of the head and neck, on the throat and on the belly. On females these markings are dark or medium grey. White Wagtails’ underparts are otherwise white, and their backs are grey. Their tails are black with fairly extensive white margins. Their wings are dark with a broad white stripe. Juveniles and birds in winter plumage have grey heads. Dark markings are visible on the chests of birds in all plumages. White Wagtails have black beaks, black legs, and dark brown irises. They are familiar, busy garden birds, often fearless when approached.
In archipelago regions White Wagtails have learnt to approach people for safety when birds of prey appear. As their name suggests, Wagtails constantly wag their long tails up and down.
