(Redirected from Red-breasted merganser)
The 'Red-breasted Merganser' (''Mergus serrator'') is a diving
duck.
Its
breeding habitat is freshwater
lakes and
rivers across northern
North America,
Greenland,
Europe and
Asia. It nests in sheltered locations on the ground near
water. It is
migratory and many northern breeders
winter in
coastal
waters further south.
The
adult Red-breasted Merganser is 52-58 cm long with a 67-82 cm wingspan. It has a spiky crest and long thin red bill with serrated edges.
Adult males have a dark head with a green sheen, a white neck with a rusty breast, a black back and white underparts. Adult females have a rusty head and a greyish body.
Juveniles are like the
female, but lack the white collar and have a smaller white wing patch.
The call of the
female is a rasping ''prrak prrak'', and the
male gives a feeble hiccup-and-sneeze display call.
Red-breasted Mergansers dive and swim underwater. They mainly eat small
fish, but also aquatic
insects,
crustaceans and
frogs.
The Red-breasted Merganser is one of the
species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (
AEWA) applies.
The Red-breasted Merganser is one of the fastest birds in level flight, having reached speeds of over 160 km/h (100 mph).
