Spectacled
Eider
Very
little is known about the Spectacled Eider because it wasn't
discovered until the 1990's Because they live in the most remote and
extreme sub-arctic environment on earth.
-IS
CURRENTLY ON THE ENDANGERED ANIMALS LIST
-The
Spectacled Eider (Somateria fischeri) is a large sea duck, which
breeds on the coasts of Alaska and northeastern Siberia.
-The
lined nest is built on tundra close to the sea, and 5-9 eggs are
laid. This species dives for crustaceans and molluscs.
-It
winters in often enormous flocks at sea in the Arctic along the edge
of the pack ice.
The
Spectacled Eider is slightly smaller than the Common Eider at
52-57cm.
-The
male is unmistakable with its black body, white back, and
yellow-green head with the large circular white eye patches which
give the species its name.
-The
drake's call is a weak crooning, and the female's a harsh croak.
-The
female is a rich brown bird, but can still be readily distinguished
from all ducks except other eider species on size and structure.
-Immature
birds and eclipse adult drakes are similar to the female.
-Migrating
birds
-Dive to the sea floor for food
-The Spectacled Eider evolved differently but is very similar to the common Eider
Eating
Habits:
Spectacled
eiders often feed like dabbling ducks, immersing their heads in the
water and tipping up to forage. They feed primarily on mollusks and
crustaceans in shallow waters and may forage on pelagic or
free-floating amphipods that are concentrated along the
sea-water/pack-ice interface. On coastal breeding grounds, they feed
on freshwater mollusks, small crustaceans, insect larvae, grasses,
berries and seeds. They utilize inland ponds and coastal shallows
during brood rearing to feed on crane flies and caddis fly larvae.
-Male and Female look different and make different calls, Presumably for mating reasons. Another possible reason could be because the female camouflages with the arctic tundra grasses to stay with the eggs and stay hidden from predators such as the arctic fox.
Because there was so little information some of what I have I had to make up from observation.
These are lovely. Try doing a drawing of the nest and eggs too if you haven't already.
