Facts about this animal
The goosander is a large “sea” duck, mostly found in freshwater habitats. They are excellent divers and are characterised by long bills with a hooked tip and serrated edges, used for catching fish. The body-weight of males is about 1670 g, of females about 1540 g.
Nest sites are preferably in tree cavities. 9 to 10 cream-coloured eggs are laid, which are incubated by the female alone for 32-35 days.
The food of the goosander consists mainly of fish, but also of bivalve shells, snails, leeches, aquatic lizards, crays, and frogs.
Did you know?
that goosanders are also as often known as "sawbills" because of the serrated edges to their bills?
