244 GEOLOGICAL SURVEY OF CANADA. 
Mackenzie valley to the Arctic coast. (Ross.) Throughout a 
large portion of Alaska, especially that part which is more or less 
heavily wooded and interspersed with mountains, the golden 
eagle is found. The Point Barrow party secured a single speci- 
men taken by the natives east of Colville River, It extends its 
range west along the Aleutian chain, having been obtained by 
Dall on Unga Island, who mentions it as a common resident on 
the Aleutian chain as far west as Unalaska. (JVe/son.) 
The golden eagle is not rare in the vicinity of St. Michael. It 
is more [frequently seen further north in the vicinity of Norton 
Bay, and in the hills back of Pastolik than on St. Michael Island. 
On the Aleutian Islands it is quite a common bird. At Unalaska 
they are fully as common as the bald eagle, and are reported to 
breed in March on the high bluffs on Makushin Point. (Zzrner.) 
The twhole of British Columbia, but chiefly east of the Coast 
Range, where it is a resident ; rarely west to Vancouver Island. 
(fannin.) Resident but not common in the Lower Fraser valley. 
Not common in winter in the Cariboo district, B.C.; also in 
the winter at Lake Okanagan, B.C. (Svooks.) Rare in British 
Columbia. A few specimens seen around the higher mountains 
at Ducks and Kamloops. (S¢treator.) Seen two or three times on 
the interior mountains. As rare in British Columbia as on the 
Atlantic seaboard. (Rhoads.) 
BREEDING NoTes.—From various points along the valley of 
Anderson River Lat. 68°—69°30’ to its outlet in Liverpool Bay and 
from the mouth of the Wilmot Horton in Franklin Bay, an aggre- 
gate of twelve nests of this eagle was obtained by us in the course 
of the seasons from 1862 to 1865, inclusive, Ten of this number 
were built against the face of steep and almost inaccessible ' 
banks of shale or earth at a height of 70 to 80 feet, and from 20 to 
30 feet below the summit. One thus examined, in 1864 was found 
to be of considerable size ; it was composed of a large platform 
of built-up twigs and sticks, having a bed of -hay, moss, and 
feathers in the centre, and, as this and other similarly constructed 
nests appeared to be annually renovated prior to reoccupation, 
they must ultimately assume vast proportions, Pillaged nests are» 
however, frequently deserted for a period, but in one instance 
where the female had been snared upon her nest and the eggs 
taken it was found occupied the following season probably by the 
widowed male and another mate. In two instances only were the
