same species at Great Bear Lake in Lat. 66°. This was in the 

 spring of 1825. Ross records it north to Lapierre's House in the 

 valley of the Mackenzie. It is a common species in the wooded 

 portion of Alaska and extends west to Unalaska according to 

 Turner, ^t descends south into British Columbia east ,of the 

 "Coast Range where it is fairly common though rare on the C9ast, 

 according to Fannin. A mated pair seen at Lake La Hache, B.C., 

 by Mr. Rhoads. 



On the prairie it is seldom seen but one was taken at Medicine 

 Hat in May, 1894, and a pair in the Cypress Hills in the same 

 year. A few were observed on Old Wives' Creek, Assa., in 1895. 

 None were seen in the mountains by Mr. Spreadborough in 1890, 

 1891, 1897 and 1898, but a pair were found breeding by him in the 

 summer of 1902 at Cascade, B.C., on the 49th parallel, and a nest 

 was taken by him at Edmonton, Alta., in May, 1897.

Breeding Notes. — We have few authentic records of the 

 nesting of this bird. 



It breeds every year in the Magdalen Islands in the Gulf of 

 St. Lawrence, selecting a thick bushy place. {Rev. C.J. Young.) 

 A [pair built regularly on an island in Lake Joseph, Mus- 

 koka, Ont. (/. H. Fleming.) This falcon ranges along the 

 Anderson River almost to the Arctic coast at Liverpool Bay. 

 Several of their rests had apparently been built by them on pine 

 trees, and others on the ledges of shaly cliffs. The former were 

 composed externally of a few dry willow twigs, and internally of 

 withered hay or grass, etc., and the latter had only a very few 

 decayed leaves under the eggs. I would also mention the follow- 

 ing interesting circumstance. On May 25th, 1864, ^ trusty 

 Indian in my employ found a nest placed in the midst of a thick 

 branch of a pine tree at a height of about six feet from the 

 ground. It was rather loosely constructed of a few dry sticks 

 and a small quantity of hay. It then contained two eggs. Both 

 parents were seen, fired at and missed. On the 31st he revisited 

 the nest which still had two eggs, and again missed the birds. 

 Several days latter he made another visit thereto, and to his sur- 

 prise the eggs and parents had disappeared. His first impression 

 was that some other person had taken them. After looking care-
