Pied/White Wagtail

Motacilla alba (Linnaeus, 1758) PW PIEWA 10200
Family: Passeriformes > Motacillidae

Pied/White Wagtail, Chris Knights

The Pied Wagtail is a familiar bird and the most common wagtail species in Britain & Ireland. Its black, white and grey plumage and bobbing tail are distinctive.

The Pied Wagtail has a grey back and white face with black bib and crown. It is often seen running over the ground pursuing insect prey or 'wagging' its tail rapidly up and down. The species is confiding and frequents urban areas, gathering in large roosts on rooftops and in trees in winter. It has a characteristic "chirrup" call. It is widespread in Britain & Ireland, but is less common on higher ground in winter.

There are two subspecies of Moticilla alba. The subspecies Pied Wagtail (Moticilla alba yarrellii) is found throughout Britain & Ireland and is mostly sedentary, although ringing data show some winter movements into southern Europe. The subspecies White Wagtail (M. alba alba) is found in continental Europe, and is seen as a passage migrant.

Identifying yellow-coloured wagtails

When is a yellow wagtail not a Yellow Wagtail? These bright-coloured summer visitors are declining across much of their range and a frequent mistake is believing that any wagtail showing yellow in its plumage is this species.

This video will help you separate individuals from the more widespread resident Grey Wagtail - which despite the name always shows yellow, and even juvenile Pied Wagtails.

Status and Trends

Population size and trends and patterns of distribution based on BTO surveys and atlases with data collected by BTO volunteers.


This species can be found on the following statutory and conservation listings and schedules.



Britain and Ireland together hold almost the entire world population of the distinctive dark-backed race yarrellii (Pied Wagtail), and for this reason population changes in the UK are of global conservation significance. The CBC shows that a strong increase occurred up to the mid 1970s, such that populations have shown shallow increase overall since 1967. Since 1974, however, the results of monitoring have been somewhat conflicting: CBC/BBS and WBS/WBBS trends fluctuate in parallel but, whereas little overall change is evident in the CBC/BBS index, WBS/WBBS has shown a rapid decline, suggesting a strong influence of factors specific to linear waterways. The BBS map of change in relative density between 1994-96 and 2007-09 indicates that decrease occurred over that period throughout Scotland, away from the western coastal fringe, and in upland and urban areas of England and Wales, and increase mainly in Northern Ireland and westernmost Britain. The European long-term trend, which includes the nominate race of the species (White Wagtail), has been broadly stable since 1980 (PECBMS: PECBMS 2020a>).

Breeding Pied Wagtails are almost ubiquitous in Britain & Ireland, being recorded in 95% of 10-km squares. Upland regions have low densities, although associated river valleys and foothills can support higher numbers. Densities are highest in lowland areas of the north and west but relatively low throughout England, even in grass-dominated areas. Pied Wagtails vacate upland areas of northern Scotland and northern England in winter, and densities are generally low in the northern half of Britain. Densities are high throughout Ireland.

Breeding range has changed little and winter range has expanded slightly, mostly around the fringes of the uplands and often involving single birds or early returning breeders.

Interpretation and scientific publications about Pied Wagtail from BTO scientists.


Causes of change

The causes of change for Pied Wagtail are unclear

Further information on causes of change

The long-term trend in abundance is similar to those shown by Wren and Long-tailed Tit, two other resident insectivores (Siriwardena et al. 1998a). Modelling suggests that climate change may have had a positive impact on the long-term trend for this species (Pearce-Higgins & Crick 2019). Average clutch and brood sizes have declined a little, but this has been counteracted by a large fall in nest failure rates. The number of fledglings per breeding attempt has shown a strong linear increase.

Information about conservation actions

There are currently no conservation concerns about the Pied Wagtail, and whilst numbers have fluctuated, the causes of change are unclear and hence no specific conservation actions have been proposed.
