Bufflehead
Duck:
UK Status: Non native, but escapee's from
collections are found in the wild. These ducks are also found in private
collections an large estates.
Habitat: This duck
overwinters on protected coastal and inland waters of the southern USA.
They can be seen in winter on the Great Lakes. They breed on wooded
lakes and pools, mainly in Canada.
Breeding: Buffleheads are
monogamous, and usually return to the same nest site year, after year.
Nests are the cavities in trees, mainly Aspens and Poplars, usually
using the old nests of the Flickers (A type of woodpecker). When nesting
the females are often preyed upon by animals such as weasels and foxes.
They may also be killed by female birds of other species looking for a
nesting site. Golden-eye Ducks are notorious for this behaviour. There
are usually around nine pale buff, glossy eggs in a clutch, but there
can be as few as six, or as many as eleven. Incubation takes about a
month, and a day after the last egg hatches the ducklings fledge.
Comment: This is a highly
spirited diving duck, and it's images has been added to some 'Coats of
Arms'. Buffleheads are hunted by man, though it's numbers remain
consistent and unaffected by hunting.
