Wigeon are grazing ducks, feeding on grass or mud-flat plants - a feeding habit usually associated with geese. However, they do also feed in water and go "end-up" in a more duck-like fashion.
Their main breeding areas outside the UK is a wide Arctic and Sub-Arctic belt running west from Norway across Asia to the Bering Straight. Typical habitat is fresh water that is shallow and still, although they also nest by rivers and on coastal marshes.
Wigeon fly in formations of hundreds when moving along estuaries or mud-flats, with the drake (male) making a loud and musical "whee-ooo".
Classified in the UK as Amber under the Birds of Conservation Concern 5: the Red List for Birds (2021).
