350 MICHIGAN SURVEY, 1908. 



30 and another on September 5 at Washington Island (X, '04). Several 

 were found September 12 accompanying the large bird wave. They were 

 exceedingly shy and there might have been many present during the 

 large bird waves, which, owing to this trait, were not identified. 



24. HaUactiis leucocrpJtahis (352). Bald Eagle. 



Eange : North America at large, south to Mexico, northwest through 

 the Aleutian Islands to Kamchatka. Breeds locally throughout its 

 range. 



Note. "The birds from Alaska and much of British America are con- 

 siderably larger than those from farther south, and on this account have 

 been separated as a distinct race {Haliaeetus leucocephalus alascmms 

 Townsend)." Thus this new subspecies occurring in northern North 

 America makes the old name of the Bald Eagle (Haliaeetus leiieocepha- 

 lus) apply simply to the southern form. Without doubt the ones seen 

 here are referable to the southern form. 



Stations: Eock Harbor, III, 2; Tamarack Swamp, II, 2; Tobin Har- 

 bor, IV, 7. 

 Siskowit Lake, V, 4. 



Washington Harbor, X, '04; along Washington river, IT, 

 '04. 



Breeding; July 20 two young still in the nest. July 24 an immature 

 bird was seen at II, 2 and another at Siskowit Lake August 5. On 

 August 8 a nest with one young was seen near Siskowit Lake. 



This species was rather common when we consider how few large 

 birds of prey are usually found in a limited district. They were seen 

 at Eock Harbor, Siskowit Bay and Washington Harbor; only a lone 

 male was seen at the latter place, however, and probably none bred in 

 the vicinity. 



Breeding Notes: On the morning of July 20 when near the head of 

 Tobin Harbor (IV, 7) a large female flew out over the boat scold- 

 ing and snapping her bill, as though a nest were near. A Pigeon 

 Hawk soon attacked her, the eagle turning completely over in its efforts 

 to strike its tormentor. The male shortly made his appearance, and a 

 little further on the nest was discovered in a small ravine. It was 

 situated in a tall poplar tree about sixty feet from the ground. The 

 nest itself was very large, about five or six feet across the top and six 

 or seven feet deep, and had probably been used for several years, the 

 additions made each year soon making it quite bulky. It contained two 

 young, one of which flew from the nest when approached. An im- 

 mature bird was seen in a tamarack swamp (II, 2) near McCargoe 

 Cove on July 24. On August 5 another young bird was seen at Sis- 

 kowit Lake (V, 9) and on August 8 a nest was found about 125 yards 

 north of the same lake in a small burning. It was situated in a dead 

 Norway pine about sixty feet from the gi'ound and was composed of 

 sticks, making a mass at least four feet across. One young was in 

 the nest. As the tree was approached the old birds circled overhead 

 snapping their beaks, but did not dare to approach very closely. The 

 immature specimen was procured and proved to be nearly feathered and 

 about as large as the adults. 



At Washington Harbor an old white-headed male was a frequent 

 visitor, a dead limb of a giant white pine tree which stood near the 

 shore being its favorite perch.
