710 SYSTEMATIC SYNOPSIS. —LAMELLIROSTRES — ANSERES. 
Siberia; wintering mainly on the Aleutian Islands; usually found in company with Pacific, 
spectacled, and king eiders. Being observed to breed in a plumage resembling that of the 9, 
this eider probably requires at least two years to acquire the complete dress. The most beau- 
tiful of inany specimens I have handled have been winter birds. Eggs 7-9, 2.25 x 1.60 
exactly like those of the common eider in shape, color, and texture of shell.

Bill (in both sexes) peculiar in the extension upon it of dense velvety feathers which reach to a 
point on the eulmen beyond the nostrils, thence sweeping past the nostrils obliquely downward 
and backward to the commissure, the nostrils opening just beneath the line of feathers. Feathers 
of chin extending in a point nearly as far as those on culmen. A peculiarly dense and pufly 
patch of velvety feathers 
about the eye, suggesting 
spectacles; frontal feath- 
ers erect, pilous, in the @ 
somewhat stiffened; oc- 
cipital feathers lengthened 
into a crest; these char- 
acters of the head-feather- 
ing best marked in the @, 
but indicated also in the

Adult @: General color 
grayish-black, the neck 
and most of the back 
white; lesser and median 
wing-coverts, the curved 
tertials, the lining of wings 
and axillars, white; flanks 
white. On the head, the 
white of the neck gives

way to rich sea-green, especially on the occipital crest; the frontal feathers are also tinged with 
greenish; but the ‘spectacles’ are pure silvery white, framed in black. Bill, in the dried state, 
dingy yellowish; feet the same, with dusky webs. Smaller than the common eider; wing 
10.00; tail 4.00; tarsus 1.75; middle toe and claw 2.75; Dill only about an inch long on 
culmen, but about 2.25 along gape. Q: Greatly different, as in all the eiders. Bill black, 
with whitish nail of under mandible; feet quite dark. General plumage like that of the com- 
mon eider, barred almost throughout with black, chestnut-brown, and yellowish-brown, giving 
way on the belly to dull brownish nebulated with dusky; on the head to pale brown streaked 
or otherwise obscured with dusky, Avxillars white. Though thus so similar to the common 
eider in pluinage, the peculiar feathering of the head and bill suffices to distinguish the bird at 
a glance. Northwest coast, common in some localities, from Unalashka northward to Norton 
and doubtless Kotzebue Sound; but its ordinary range appears to be a restricted one, nearly 
coincident with that of the emperor goose.
