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

UK Birds of Conservation Concern	Amber listed
Species of European Conservation Concern	Least Concern
IUCN Red List of Threatened Species (global)	Least Concern
Schedule 1 license required (to disturb)	No
Birds Directive Annex 1	No
Listed on the Annexes of	WCA(II,III), WBD(II*,III*), Bern(III), Bonn(II), AEWA

The Wigeon is best known to most UK birdwatchers as a winter visitor, especially to coastal marshes where it feeds in large flocks. However, small numbers bree,d mostly in Scotland and northern England. The mean number of pairs reported to the RBBP was 216 for the five-year period 2015–2019 but the species is under-reported and the recent and longer term trends are not known.

UK winter population

-11% decrease (1995/96 to 2020/21)

In winter, there are concentrations of Wigeon in the Northern Isles, the inner Moray Firth, parts of central Scotland, the Irish Sea coastal fringe, major river valleys in eastern England, estuaries of south and southeast England and the rivers, lakes and turloughs of the west midlands of Ireland. The main breeding areas are in the Pennines and in northern Scotland.

Wigeons are common winter visitors, recorded on up to 20% of lists but scarce in summer when there is a small over-summering population and small numbers breed.

Causes of change

The trends in the European flyway population since 1988 are believed to have been mostly caused by climatic effects, which influence breeding productivity and may also have a marginal effect on overwinter survival (Fox et al. 2016). Decreases in Equisetum stands on breeding lakes have also been suggested as a potential driver of declines in Sweden and Finland (Pöysa et al. 2017). In the absence of UK-specific information (or knowledge about the UK trends), it is not known whether climatic or habitat conditions or other factors may be influencing UK breeding population changes.
