Spectacled eiders are diving ducks that spend most of the year in marine waters where they primarily feed on bottom- dwelling molluscs and crustaceans.
Spectacled eiders typically winter south and southwest of St. Lawrence Island in the central Bering Sea; they wintered in the same place in 4 of the 5 years since the discovery of their wintering area.
Thus, recent minimum population estimates for the number of pairs of spectacled eiders comprising the North Slope breeding population are as follows: for 1993: 3,669; for 1994: 2,828; for 1995: 2,803; for 1996: 2,179; for 1997: 2,107; for 1998: 3,800; for 1999: 2,679; and for 2000: 2,567.

 Eiders: Wildlife Notebook Series - Alaska Department of Fish and Game
The common eider (male) is the only eider with a fl cap extending to the forehead and around the eye and divided on the crown by a white streak originating from the hind neck.
Common eiders nest near driftwood or clumps of grass on barrier islands, sandy beaches, and on islands in tundra ponds, often in association with gull colonies.
The male spectacled eider's distinguishing marks are a fl chest, unlike other eiders, and a large pale green head with fl outlined white spectacle-like patches around the eyes.

The eiders - which include the spectacled, Steller's, king, and common - are marine diving birds of Arctic and northern coasts.
There are three distinct breeding populations of spectacled eiders worldwide: in the Yukon-Kuskowim (Y-K) Delta and North Slope regions of Alaska; and along the north coast of Siberia in Russia.
Spectacled eider numbers on the Y-K Delta (western Alaska) have fallen precipitously - by some 96% between the mid-1970s and the early 1990s, from an estimated 48 000 nesting pairs to less than 2500 pairs.

 Observations on the Day-old Young of the Spectacled Eider, Somateria Fischeri
Furthermore, it is conceivable that the molting "spectacle" would take on an even more linear appearance in a dried specimen, and the artist, faithful to his eye, could justifiably interpret this as a narrow circle or "question mark." Only one of the four Spectacled Eiders survived at Round Lake.
The eiders "sat" a good deal during their first two days, usually resting on the belly, but sometimes on the heels, with backs nearly upright and breasts high, the bills touching the puffed-up breasts and the heads drawn back.
The bill was light, opaque grayish blue, straight-sided, with a brownish-red nail; the egg tooth was creamy white to pinkish yellow; the iris was dark brown; the tongue and the lining of the mouth were dull, pale pink; the feet were dark umber gray, lighter on the sides of the toes.

Spectacled eiders are diving ducks that spend most of the year in marine waters where they primarily feed on bottom-dwelling molluscs and crustaceans.
The Spectacled Eider Recovery Team was formed, consisting of seven members and four consultants with a variety of expertise in spectacled eider biology, conservation biology, population biology, marine ecology, Native Alaskan culture, and wildlife management.
Only one spectacled eider was observed among 420,000 eiders migrating past point Barrow during spring (Woodby and Divoky 1982) suggesting that either the timing of this survey was not concurrent with spectacled eider spring migration, or spectacled eiders do not migrate along the Beaufort Sea coast in spring.

The destruction of habitat is not known to be a factor in the decline of the spectacled eider.
Spectacled eiders may also be exposed to environmental pollutants including heavy metals and organochlorines in the marine environment, with potential effects on survival and reproduction.
Spectacled eiders may use coastal waters of the Beaufort Sea for brief periods, but Myres (1958) presented evidence that their principal migration routes between the Chukchi Sea and North Slope breeding grounds are over land.

The condition of spectacled eider habitat in Siberia is less certain, but it is apparently good enough to host over 90 percent of the remaining world population.
Tests run on spectacled eider blood samples indicate that 13 percent of females pick up lead during the 2-3 week interval between their arrival on the nesting grounds and the initiation of incubation.
The relative importance of lead in the decline of the Y-K Delta spectacled eider population continues to be studied.

The spectacled eider differs from other eiders in that its feathers extend down to the nostrils on the bill, which is bright orange on males and blue-gray on females.
Although traditional subsistence harvest likely did not have a significant effect on historically larger eider populations, it may be contributing to the bird's current decline now that the eider population is smaller.

It is even more mysterious since Spectacled Eiders spend nine to eleven months (females and males, respectively) at-sea, and flocks of birds have not been reported.
These birds congregate in very dense flocks far from land, they frequent areas few vessels visit in summer and fall (and none in winter), and they are easily missed if the survey plane is not within a few km of a flock.
Based on that location, Bill Larned flew to that general area and located dense flocks of Spectacled Eiders in holes in the pack ice north-east of St. Matthew Island, Alaska.

The females and downy young of all three of these eiders are closely similar to one another in all respects except the leathering of the facial region, which reflects to a lesser degree the differences exhibited by the males.
Judging from the literature, there seem to be no trenchant differences in reproductive habits or behavior between fischerl on the one hand and mollissima on the other.
I therefore heartily endorse the recommendation of Delacour and Mayr (Wilson Bull., 57: 33, 1945) that the Spectacled Eider be known henceforth as Somateria fischerl (Brandt).--KT C. PAmrs, Carnegie Museum, Pittsburgh 13, Pennsylvania.

On February 8, 2000, the Service published a proposed rule (65 FR 6114) to designate critical habitat for the spectacled eider, and on March 13, 2000, the Service published a proposed rule (65 FR 13262) to designate critical habitat for the Alaska-breeding population of the Steller's eider.
Based upon the previously published proposals to designate critical habitat for the spectacled eider and Steller's eider and comments previously received during the comment periods, we have conducted a draft economic analysis of the proposed critical habitat designations.
The development of the economic analyses for the proposed critical habitat designations was unexpectedly delayed, and we subsequently extended the comment periods through August 31, 2000, with the expectation that the economic analyses would be available by August 1, 2000.

The reasons are unknown, but some factors may be an increase in predators relative to eider numbers and the ingestion of lead shot.
The wintering sites of the Spectacled Eider, openings in the ice in the frozen Bering Sea, were not discovered until 1995.
Discussion During the winter the Spectacled Eider's diet consists largely of mussels and other mollusks, which it captures in deep dives over submerged ledges and reefs, but on its tundra breeding grounds this duck feeds mainly on aquatic insects, crustaceans, and the seeds of water plants.

 Lead shot affecting spectacled eider populations in Alaska   (Site not responding. Last check: 2007-09-17)
Declines in spectacled eider populations on the Yukon-Kuskokwim Delta (Y-K Delta), Alaska, are likely the result of the birds ingesting lead shot, according to a recent study in the Journal of Wildlife Management.
Populations of the birds on the Y-K Delta declined rapidly during the 1980s, and low adult female survival was suggested as the likely cause of the decline.
The authors of the new study researched annual survival rates of adult female spectacled eiders at two sites on the Y-K Delta during 1993-96 and found evidence that, although survival rates may differ among sites, lead exposure influences survival.
