Figure 23. Distribution of 36 King Eiders accepted through 2003. Six out of every ten have been found along the coast between Sonoma County and Monterey Bay. Presumably reflecting differences in observer coverage, more records come from the state’s southern third than from the northern third.

Figure 24. This first-year female King Eider was photographed on 30 December 1982 in Emeryville, Alameda County, where it was present from 19 December 1982 to 7 May 1983. This bird’s bill shape and V-shaped flank markings rule out a female Common Eider (1983-007; Rick LeBadour).
Figure 194. This King Eider, photographed on 5 December 1982 at Imperial Beach in San Diego County, was a second-year male as judged by bill morphology and dark feathering in the secondary coverts. The species still has not been found farther south along the Pacific coast (1982-109; Richard E. Webster).

Figure 195. The rigors of a winter and spring spent well south of the normal range show in the tattered plumage of this second-spring male King Eider, photographed on 28 May 1992 at Redondo Beach, Los Angeles County (1994-130; Jonathan K. Alderfer).

This duck is a holarctic breeder. Old World birds winter along the coasts of Greenland, Iceland, Scandinavia, and Kamchatka; New World birds winter rarely on the Great Lakes and along the Atlantic coast to Virginia, casually south to Florida and along the Gulf coast to Texas. In the West, the species winters in the southern Bering Sea, among the Aleutian and Shumagin Islands, and east to south-central Alaska. Vagrants occur casually along the Pacific coast south to southern California and accidentally in the continent’s interior.
A first-winter female King Eider collected on 16 December 1933 “from a group of three” at Tomales Bay in Marin County (Moffitt 1940a) provided the first verifiable record for California. Reports from “off Blackpoint, San Francisco,” San Francisco County, during winter 1879/1880 (Henshaw 1880) and from Suisun Marsh, Solano County, 15 October 1902–1 February 1903 were not documented (Dawson 1923). The accepted records, all from coastal areas, are concentrated in the middle third of the state (Erickson and Terrill 1996; Figure 23). Birds have summered on Monterey and San Francisco Bays and in Ventura County, but the species is mainly a late fall and winter vagrant to the state, with about 75% having occurred between 18 October and 4 April, often among scoter flocks.
Mlodinow (1999b) noted a decrease in this species’ frequency as a vagrant along the Pacific coast starting in 1987, a negative trend that concords with a 56% twenty-year decline (1976–1996) in the counts of King Eiders migrating past Pt. Barrow, northern Alaska (Suydam et al. 2000).
