Goosander (Common Merganser) Mergus merganser
The wintering population of Goosanders in Norfolk has never been particularly numerous, though it seems to have increased a bit in recent years. Sparham Pools and Denver Sluice are two of the most reliable sites, though individuals may occur on any suitable river or lake.
A pair bred in Norfolk for the first time ever in 2007.
North American birds of the race americanus differ slightly from European birds of the nominate race, for example they have a slightly deeper bill-base. The alternative name "Common Merganser" is usually used instead of Goosander in North America.
