BTTFFLE-HEAD. 51 
Clang-ula islandica n rmel. I . Barron ( tolden-eye. 
Breeding range.- A few breed in eastern Canada from the Gulf of 
Saint Lawrence (Point des Moots) t<> northern Labrador (Davis Inlet). 
A few are found in Greenland during March and April ami in Novem 
ber and December as far north as rlolstenborg, 67 latitude, bui the 
species apparently does n<>t breed there, though breeding quite com- 
monly in Iceland. The principal summer home is in the Rocky Moun- 
tains, where the species breeds from southern ( Iolorado< I >olores< lounty) 
north almost to the Arctic coast (Fori Anderson), though north of the 
United States there are only a few records in the entire district. On 
the Pacific slope the species breeds quite commonly in central British 
Columbia and less commonly north to Lake (Mark, Alaska. The most 
southern record of breeding on the Pacific slope S66ms to he the one 
made by one of the parties of the Biological Survey at Paulina and 
Diamond lakes, Oregon. 
Winter r<in<je. — The larger number of the breeding birds of eastern 
Canada spend the winter around the Gulf of St. Lawrence, but a few 
straggle south and have been recorded at this season from Maine. New 
Hampshire, Massachusetts, New York, Virginia, and on four occasions 
from North Carolina. In the interior they have been recorded a few 
times in tin 4 States around the Great Lakes and even in Nebraska. 
The Rocky Mountain breeding birds pass in winter scarcely south of 
their summer range and are found from southern Colorado (Fort Lewis) 
to Montana (Fort Sherman and Great Falls). The Pacific birds win- 
ter from southern Alaska (Portage Bay) to California (San Francisco). 
Spring migration. — Records of this species are too few to allow of 
exact statements in regard to its migration; indeed, over most of the 
range of the species the winter and summer homes overlap. Migrants 
were noted at Quebec City, April 14, 1899, and April 16, 1901. One 
was seen near Asheville, N. C, in 1893 as late as May 6. One was 
taken at Fort Anderson, Mackenzie, June 14, L864. 
In Iceland the species begins breeding in May or early June. At 
Godbout, Quebec, young were found July 11, 1881. Incubated eggs 
Were taken June 17 in central British Columbia. 
F<i1 1 migration. — The earliest fall migrants in L897a1 Montreal were 
seen October 23. One was taken near Washington, D. C November 
22, 1889, and one at Lake Koshkonong, Wisconsin, November L4, 1896. 
Charitonetta albeola (Linn.). BuHle-head. 
Breeding r<tn<j<>. — In the nesting season the buffle-head is almost 
wholly confined to Canada, but a few breed in Wisconsin (Pewaukee 
Lake), northern Iowa (Storm-, Clear, and Spirit lakes), Wyoming 
(Meeteetse Creek), Montana (Milk River, Mat head Lake). It is a 
tolerably common breeder in the northern two-thirds of Ontario, and
