Ruddy ducks are small, stout freshwater diving ducks with broad, short wings and narrow, stiff tails. Originally from North America they were introduced in the UK in order to enhance ornamental wildfowl collections. Subsequent escape and successful establishment outside of the UK has resulted in a European conservation problem due to them hybridising the white-headed duck.
Associated with lowland wetlands and open fresh water, they breed on reservoirs, gravel pits and lakes with weedy fringes. In winter, they flock to concentrate on large open waters, often water supply reservoirs.
Its diets consists mainly of aquatic insect larvae and plant seeds.
Incubation: 25 days
Fledging: 50-55 days
