Spring migration. After severe winters, when they have been 
driven away by the ice, American eiders return to Prince Edward 
Island about the last week in March and to Newfoundland the iirst of 
April. The last are seen on the Massachusetts coast in April (April 
Is. L890; April 20, L891; April L2, is 1 .':); April 20, L894; an unusually 
late bird was seen May L8, L892). Eggs were found at Grand Manan, 
New Brunswick, May 31, L833, ami young on the south coast of Lab- 
rador July 4. L860. 
F,ill migration. — They first appear off the Massachusetts coast early 
in November, occasionally in October (October 10, 181K); October 30, 
L892), and are common by the end of November. 
Somateria v-nigra ( J ray. Pacific Eider. 
Breeding range. — The principal summer home of this eider is on the 
coasts and islands of Bering Sea and along the coast of the Arctic 
Ocean between the mouths of the Mackenzie and the Coppermine 
rivers. The species breeds west to the northeastern coast of Siberia 
and south to Cook Inlet, Kadiak Island, the Aleutians. Near, and 
Commander islands; it is accidental in the interior at Great Slave Lake 
and at Lawrence. Ivans. It is probable that the eiders so abundant 
on Banks Land belong to this form and that a few range north to 
Melville Island. 
Wintt r range. The species seems to be massed during winter at the 
southern portion of the breeding range in the vicinity of the Aleutians. 
Spring migration. Early arrivals are sometimes seen near the 
mouth of the Yukon the last of April, but usually they appear about 
May 10. At Point Barrow the dates of arrival are May 16, L882, and 
May li>, L883. On the Kowak River eggs were found June 2, and the 
young appear about the first of July. Incubation seems to be simul- 
taneous over all the district from the mouth of the Yukon to that of 
the Anderson. 
/•</// migration.- Pacific eiders seem to disappear from all points in 
their sum me i- haunts at about the same time, the first week in October, 
but for several weeks previously numb rs migrate along the north coast 
of Alaska. Many individuals winter and summer in the same locality, 
while the birds breeding about the mouth of the Coppermine River 
migrate at least 2,000 miles. 
Somateria spectabilis (Linn.). King Eider. 
Breeding range. 'The king eider breeds in the arctic regions. It 
is abundant on the west coast of Greenland, breeding from latitude 66°
