274 GEULOGICAL SURVEY OF CANADA. 
Very rare at Aweme, Man. One shot, October, 1906, while after 
poultry. (Criddle.) One specimen was shot at Comox, Vancouver 
island, October, 1894, by W. Harvey. (Kermode.) A _ regular, 
though scarce, fall and spring visitor at Chilliwack, B.C. (Brooks.) 
Throughout all Alaska, from the Aleutian islands north, both along 
the coast and through the interior, extending from Bering strait 
across the northern portion of British America, the present falcon is 
the commonest bird of prey. It frequents the vicinity of cliffs and 
rocky points about the sea coast, or the rocky ravines of the interior 
during the breeding season, and the remainder of the year, especially 
in the fall, it is found wandering over the country everywhere that 
food can be obtained. (Nelson.) Several specimens of this gyr- 
falcon were obtained in the vicinity of St. Michael, where it is a 
constant resident, with probably exceptions during protracted periods 
of very severe weather. The natives assert that this bird breeds on 
the high hills, either on a rocky ledge or on the moss-covered ground. 
(Turner.) An adult female was taken at Muller bay, Alaska. 
(Anderson.) One specimen was collected by Elliott on St. Paul 
island, Bering sea, and Dr. Bean shot one at sea about 60 miles 
southeast of St. George island. (Palmer.) The only hawk obtained 
at Point Barrow was of this variety. Hawks were seen in 1882 and 
1883, but were always very wild and difficult to approach. (Mur- 
doch.) Observed numerous individuals along the Kowak, Kotzebue 
sound, Alaska, during 1899. (Grinnell.) Two specimens taken at 
Point Barrow, Arctic sea, Alaska, September, 1897. (Wztmer Stone.) 
BREEDING NotTes.—This gyrfalcon is common in the wooded 
country on both sides of the Anderson river. Over 20 nests were 
secured, and with only two exceptions which were built one on a 
ledge of rocks and the other against the side of a deep ravine, they 
were found close to or near the top of the tallest tree of the neigh- 
bourhood. They are similar in composition, but smaller in size 
than those of the bald eagle; and while the number of eggs was 
either three or four, their contents were frequently found in different 
stages of development. The earliest date for finding a nest was 
May t1oth. The eggs were quite fresh, though one taken five days 
later contained partially formed embryos. In a few cases young 
birds were in the same nest along with the eggs, the contents of 
which were but little changed, and in another an egg perfectly fresh 
was found with several ready to hatch. This falcon is supposed
