Eiders are relatively large seaducks that nest in colonies around the coasts of northern UK, and as far south as Walney Island in Cumbria. Once hatched, the chicks often gather together in a large 'crèche' looked after by a number of females.
How to identify
The male eider is a black-and-white duck, with a pale green patch at the back of the head, pinkish breast and pale yellow-grey bill. The female is greyish-brown with delicate barring.
Did you know?
Female eiders line their nests with soft feathers, or 'down', from their breasts. These feathers were so prized for stuffing pillows and quilts, that the eider nearly became extinct in the 19th century.
