Common Merganser
Length--25½ in.
Weight--2½ lbs.
This species is larger than the red-breasted merganser, and is one of
the largest of our ducks. It is one of the last to migrate south, and is
more common than the red-breasted merganser on inland waters.
Flocks move in follow the leader style, low over the water.
The only call seems to be a startled croak.
