352. Bald Eagle. 
Halieetus leucocephalus alascanus C. H. TOWNSEND. 1899. 
Though typical leucocephalus probably occurs in eastern Canada the 
references cannot, in default of specimens, be separated and all are 
left here. Mr. Fleming finds that all Toronto specimens are refer- 
able to alascanus. 
A pair of this species was seen on August 17th, 1896, by Mr. A. 
P. Low near Ungava bay and one by Mr. Spreadborough at East 
point, James bay, June 8th, 1904. Preble says this bird is occa- 
sionally seen at Fort Churchill, Hudson bay. Though far from 
common, it breeds in suitable situations in Newfoundland, Nova 
Scotia, New Brunswick, Quebec, Ontario, Manitoba, and westward 
to the Pacific. In its northern range in the Mackenzie river valley it 
descends to the Arctic coast. It is extremely common on the coasts 
of British Columbia and very common in the interjor of the pro- 
vince. Passing to the north it becomes still more abundant on the 
Aleutian islands. 
Very common on Queen Charlotte islands in 1900. A number of 
specimens were seen at Lake Clark, Swan lake, Malchatna river and 
Becharof lake, Alaska, in 1902. (Osgood.) Common along the 
Inside passage, especially near Wrangell narrows, Alaska. In the 
interior this bird is much rarer though I saw one at Log Cabin and 
another at Bennett, Yukon. We saw the birds occasionally about 
lakes and once or twice along the river, the last being observed near 
the White river, July 31st. (Bishop.) One set of eggs taken at 
Muller bay, Alaska, May 22nd. (Anderson.) The natives say it is 
occasionally seen about the Pribilof islands, Bering sea.  (Palmer.) 
While collecting on the Bay of Chaleurs at Port Daniels near 
Gaspé in August, 1882, the writer amused himself watching a fish 
hawk trying to supply its young with flat-fish caught in the shallow 
waters of the bay. At some distance from the shore on the margin 
of the forest were a series of large trees that had been killed by fire. 
In a tall one of these an eagle usually stationed himself and kept 
an eye on the hawk. As soon as the hawk caught a fish the eagle 
would move out in pursuit and then would commence a series of 
gyrations by both birds. The aim of the eagle was to get above 
the hawk and if he failed to accomplish this the hawk won. If
