NORTH AMERICAN BIRDS. 



as May 17, l)efore tlie ice had given way in the livers ; and in his tables 

 of phenomena observed at the Cumberland House, in latitude 54°, we also 

 observe tliat a White-headed Eagle was seen as early as the 24th of Alaich, 

 " being aluiost always the first of the sununer birds which arrives." 



Mr. MacFarlane found these Eagles breeding on Lockhart Iliver, latitude 



67° 30', but does not 

 regard it as abundant 

 in that locality, and 

 from the information 

 he has received from 

 the Indians, he pre- 

 sumes latitude ()8° to 

 be its extreme north- 

 ern range. In the fol- 

 lowing year, 1862, this 

 suj)])(i.sition was in part 

 confirmed by his find- 

 ing a i)iiir breeding on 

 the .same river, near its 

 junction with the An- 

 derson, in latitude 68° 

 north. ]\Ir. B. II. L'oss 

 states that it ranges to 

 the Arctic Circle, and 

 is numerous around 

 Great Slave and Bear 

 Lakes. It proved to 

 very common at Sitka, where Bischoff obtained a number of si)ecimens. 



Dr. Cooper, during his journey northward to the 49th degree, found this 

 one of the most abundant birds of the Falcon tribe in Washington Terri- 

 tory, particularly along the Columbia Iliver. It is a constant resident in 

 the Territory, and is said to lay its eggs as early as February. He saw largo 

 numbers along the Columbia, sitting on some log or cliff over the water. 

 He never met with it about high mountain tops nor on the plains east of 

 the Kocky Mountains. 



Dr. Newberry mot \\ith this Eagle in the interior of Northern California, 

 along the Sacramento and San Joa([uin Bivers. He found it very connnon at 

 the Cascades of the Columbia, at the Falls of the Willamette, and still more 

 al)undant about the chain of lakes in the Klamath l)asin, and also in the 

 Cascade Bango, among the mountain lakes, and wherever fish was attainable. 

 They exhibited little shyness, and wore easily 1)rought within rifle range. 



In Fhnida, Mr. Allen found this l)ird very common, breeding as early as 

 January. It was very abundant on the upper St. .Tolni's, and es])ecially so at 

 Lake Monroe. It is also equally common in Texas, according to Dresser, 



Haliaftu.1 leucacephaim.
