410 GEOLOGICAL SURVEY OF CANADA. 
as the young nestlings are often exposed to 15° below zero. On 
March 18, 1900, Dr. George found a nest containing one egg: 
This nest was also found in a willow. It will be seen, therefore, that 
this bird is the earliest breeder of all Canadian birds, having eggs 
in Alberta in the middle of March, at a time when the thermometer 
registered below zero. I have yet another set of eggs and nest 
that were collected by Mr. Hugh Richardson in Saskatchewan, 
April 2, 1896. (W. Raine.) 
484a. Rocky Mountain Jay. 
Pertsoreus canadensis capitals BAIRD. 1873. 
Only seen in the Rocky mountains at lat. 49°, where, however, 
it was common and doubtless bred. The specimens secured in this 
locality show the restricted dark areas of the head, upon which 
the variety capitalis is based. [(Cowes.) Observed on Sheep 
mountain, Waterton lake, Rocky mountains, in July, 1895; quite 
common and breeding at Banff, Rocky mountains, in the summeT 
of 1891; common high up in the Rocky mountains from Moose 
mountain, south of the Bow river pass to Crow Nest pass in July: 
1897 ; seen at Pass creek, near Robson, B.C., and was common 
in the Gold range, B.C., in 1889 ; on June 6, 1890, a young one 
was shot at Deer park, Lower Arrow lake, B.C. ; one pair seen, 
on the mountains between the North Thompson river and the 
Bonaparte at an altitude of 4,500 feet ; observed near Cascade, 
B.C., and on Sophie mountain, altitude 4,000 feet, on the Inter- 
national Boundary, in the summer of 1902; observed several at 
Elko, B.C., May, 1904. (Spreadborough.) An abundant winter 
resident in Cariboo, B.C.; I tried hard to find nests but failed; 
I believe the eggs are laid about March 25th; common in winter 
at high elevations at Lake Okanagan, B.C. (Brooks.) I noted 
these jays at Lac La Hache, Bonaparte, Vernon, Nelson and Field 
in British Columbia. (Rhodes.) 
484b. Alaskan Jay. 
Perisoreus canadensis funufrons RipGw. 1880. 
The only specimen brought home of this short-billed jay was 
killed on the roof of the dwelling house at Fort Franklin. (Rechard- 
son.) This form is the only Perisoreus found throughout the Sitkan
