Birds by name
Conservation status: Introduced
Ruddy ducks are small, stout freshwater diving ducks with broad, short wings and narrow, stiff tails. The male ruddy duck has a bright chestnut body, black crown, white cheeks and blue bill. They swim buoyantly, often with the tail cocked up, and can also gradually submerge without diving. They hardly ever leave the water, being very ungainly on land. This species is subject to a Government-led eradication programme. As a result, the UK population of ruddy ducks now stands at fewer than 150 individuals.
Swans, ducks and geese (Anatidae)
The UK's ruddy ducks are concentrated in the West Midlands, northern England, Anglesey and southern Scotland, where they can be seen on large lakes and reservoirs.
At any time of year, though they are very secretive during the breeding season. They can gather in flocks on reservoirs in winter.
Aquatic insect larvae and plant seeds.
* UK breeding is the number of pairs breeding annually. UK wintering is the number of individuals present from October to March. UK passage is the number of individuals passing through on migration in spring and/or autumn.
