Habitat and Distribution
Their breeding habitat is marshes and lakes with a metre or more water depth. Pochards breed in much of temperate and northern Europe into Asia. They are migratory, and winter in the southern and west of Europe. In the British Isles, birds breed in eastern England and lowland Scotland, in small numbers in Northern Ireland with , and in the Republic of Ireland. Large numbers overwinter in Great Britain, after the birds retreat from Russia and Scandinavia.
These birds feed mainly by diving or dabbling. They eat aquatic plants with some molluscs, aquatic insects and small fish. They often feed at night, and will up-end for food as well as the more characteristic diving.
