Conservation status: Green

These handsome diving ducks are a member of the sawbill family, so called because of their long, serrated bills, used for catching fish. A largely freshwater bird, the goosander first bred in the UK in 1871. It built up numbers in Scotland and then since 1970 it has spread across northern England into Wales, reaching south-west England. Its love of salmon and trout has brought it into conflict with fishermen. It is gregarious, forming into flocks of several thousand in some parts of Europe.
