Red-breasted Merganser

Scientific Name: 
Mergus serrator

The Red-breasted Merganser is a medium-sized duck and a member of a group known as the 'sawbills' after their long, narrow bills with saw-like 'teeth' which are good for gripping fish. A long, streamlined bird, the Red-breasted Merganser is perfectly shaped for swimming after fish. Red-breasted Mergansers are gregarious birds, forming flocks of hundreds of birds in winter.

How to identify: 
The Red-breasted Merganser is a white diving duck which can be distinguished from the Goosander by its thinner bill, grey sides, reddish-brown breast and crest of green feathers on its head.
Where to find it: 
Nests on lakes and rivers in the north and west of Britain. A common winter visitor to coastal waters.
How people can help: 

Red-breasted Mergansers are excellent at fishing, but their diet of Salmon and Trout has brought them into conflict with fishermen making a living. The Wildlife Trusts work closely with fishermen, farmers, landowners and developers to ensure that our wildlife is both protected and provides a benefit to local people. Careful habitat management on local nature reserves is one way in which local Trusts are helping to provide areas where birds like the Red-breasted Merganser can thrive and avoid conflict. By volunteering for your local Trust you can help too, and you'll make new friends and learn new skills along the way.
