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. It descends south into British Columbia east of the 
Coast Range where it is fairly common though rare on the coast, 
according to Fannin. A mated pairseen 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 4gth paraliel, and a nest 
was taken by him at Edmonton, Alta., in May, 1897. 
I found the pigeon hawk quite common during August along 
the Kowak, Kotzebue Sound, Alaska. (Gvennell.) 
BREEDING Notres.—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./. 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, a 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- 
fully around he perceived both birds at a short distance and this
