Figure 4.7.8. King eider satellite
tracking locations from year
round tracking of birds implanted
at moulting localities in Umiarfik
and the fjords at the west coast of
Disko and at a breeding locality in
Arctic Canada outside the map.
The scattered dots in the central
Baffin Bay and on Baffin Island
are from bird migrating to and
from breeding localities in Arctic
Canada west of the map border.
Observations from two ship
based surveys are also indicated
on the map. The importance of
the waters west of Disko Island,
Store Hellefiskebanke (at c. 68°
N) and Fyllas Banke (at c. 64° N)
is apparent. Based on AU/GINR
data and Mosbech et al. (2006a).

King eiders have been recorded in very large flocks (>30.000 indvs.) in leads
in the drift ice and such concentrations are very sensitive to oil spills, as a
large fraction of the entire population may be exposed to oil.
The king eider is listed as Least Concern (LC) on the Greenland Red list
(Boertmann 2007). However, this applies to the breeding population in Arctic
Canada, which are the birds that moult and winter in West Greenland.
The global status of the king eider is also Least Concern (LC) (IUCN 2010).
Long-tailed Duck, Clangula hyemalis
This duck breeds scattered along sheltered coasts, and there are no major
concentrations of moulting birds known from the assessment area. But in
winter the ducks, at least from Iceland and Northeast Greenland, winter in
the assessment area together with local birds (Lyngs 2003, A. Mosbech
unpubl.). A survey in March 1999 resulted in an estimate of 94,000 wintering
