CATALOGUE OF CANADIAN BIRDS. 271 
Shuswap lake, British Columbia, in July, 1889, I saw a nest in a 
large cottonwood tree about forty feet from the ground, near the 
shore of the lake. Nest very large, made of sticks and must have 
been three feet in diameter. The young were as large at this time 
as old birds. The young feed a good deal on dead fish that float 
ashore and also upon carrion. Common throughout Vancouver 
island. At Comox shot many specimens both young and old. At 
this time, June, 1893, they were feeding on the singing fish which 
they caught from under stones when the tide was out. (Spread- 
borough.) 
Several nests were found with eggs and young in them on Lock- 
hart and Anderson rivers. They were built on high trees close to 
the river banks and composed of dried sticks and branches lined 
with deer hair, mosses, hay and other soft materials. There were 
from two to three eggs in each nest. In one instance the parents 
made hostile demonstrations when their nests were being robbed, 
but they generally flew away and kept at a safe distance. They 
are not very numerous, and it is very doubtful if any breed to the 
northward of Fort Anderson, lat. 69° 30’. (Macjarlane.) 
This bird nests in Muskoka and in northern Alberta. I have six 
clutches of eggs, some of which were taken in northern Ontario and 
the others in northern Alberta. (W. Raine.) May 16th, 1897, a 
set of two partly incubated eggs was taken from a nest on Raza 
island, Toba inlet, Gulf of Georgia, B.C., by Charles Collier. The 
nest was in a tree about 90 feet from the ground. It was at least 
four feet across and built of sticks. In the middle on the level top 
there was an inner nest about 16 inches across with a slight depres- 
sion in the centre where the two eggs lay. The inner nest was 
almost entirely composed of moss. (W. Harvey.) 
CL. FALCO. Linnazus. 1758. 
353. White Gyrfalcon. 
Falco islandus BRUNN. 1764. 
Common in Greenland. (Winge.) In summer more common in 
the northern inspectorate of Greenland than in the southern, but 
occurring according to Dr. Finsch also on the eastern coast. The 
limits of its breeding-range in either direction have not been deter-
