Overview

The Goosander is the larger of the two sawbill ducks likely to turn up on the Sefton Coast. The drake is one of the most handsome of all ducks — salmon-pink suffused white body, bottle-green head, red serrated bill. Less coastal than the Red-breasted Merganser, Goosanders are more likely to appear on freshwater at Marshside. They breed in Scottish rivers, nesting in riverside trees.
