Goosander

Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. Kate Humble presents the goosander. Goosanders are handsome ducks and belong to a group known as 'sawbills' because their long slender bills are lined with backward pointing 'teeth', for gripping slippery fish. Underwater they're as agile as otters, chasing fish in raging currents or nosing for them under riverbanks.
