CATALOGUE OF CANADIAN BIRDS. 27I 



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'. (Macfarlane.) 



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 i6th, 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 shght depres- 

 sion in the centre where the two eggs lay. The inner nest was 

 almost entirely composed of moss. {W. Harvey.)

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-
