Wigeon Grazing Duck Ecology and Winter Flocks

The wigeon is a grazing duck that forms large winter flocks on coastal grazing marshes and estuaries, feeding on short grass and marine vegetation rather than water.

Key Facts

Wigeon are predominantly grazers, feeding on short grass and eel grass in coastal areas
UK winter population around 440,000 birds, one of the most numerous wintering ducks
Male has chestnut head with cream forehead, making it one of most distinctively plumaged ducks
Breeds in small numbers in Scotland and northern England, majority winter visitors from Iceland/Russia
Famous for the high-pitched whistling call of males in winter flocks

Welfare Considerations

Wigeon welfare depends on the maintenance of coastal grazing marshes with short turf, eel grass beds, and salt marsh. Loss of coastal grassland to agricultural improvement or development reduces wintering habitat significantly.

What You Can Do

Support conservation of coastal grazing marsh through organisations like RSPB and Wildlife Trusts
Respect winter wildfowl flocks by keeping distance to avoid flushing stressed birds
