nested regularly in the township of Oso in Frontenac county, Ont., 

 up to 1 90 1, but will probably soon cease to do so as the larger timber 

 is rapidly being cleared away. It seems to affect woods where 

 beech and black birch are plentiful, not far, however, from a growth 

 of evergreens. (Rev. J. C. Young.) 



This bird is generally distributed in the forest country north 

 of the prairie. Richardson records it from Jasper House in the 

 Rocky mountains, and describes one shot from the nest on the 

 Saskatchewan, May 8th, 1827. He also speaks of another taken 

 at York Factory, Hudson bay, August 14th, 1822. Apparently it 

 has the same range yet. (Macoun.) This species is confidently 

 believed to breed, in small numbers, however, between Fort Good 

 Hope and the Anderson, Mackenzie district. (Macfarlane.) Toler- 

 ably common in autumn and winter at Aweme, Man. A few remain 

 to breed. A nest was found high up in a tree containing four fresh 

 eggs on April 29th. (Criddle.) 



I have eggs from Oak lake and Crescent lake, Sask., and also 

 sets from Alberta. I have a set of two eggs that was taken by 

 Mr. Wenman at Stedman river. Alberta; the female was shot and 

 is now in my collection. I have another set of three eggs collected 

 by Dr. George in northern Alberta, May loth, 1894. The female 

 of this nest was also shot by Mr. Wenman. Dr. George also took 

 a clutch of four eggs out of this same wood in May, 1893. It makes 

 a large nest of sticks, weeds and roots, and builds in the highest 

 tree tops. The American goshawk is a rare summer resident in 

 northern Manitoba, but is more plentiful in northern Saskatchewan 

 and Alberta. The eggs are bluish white, unmarked, although they 

 are sometimes nest-stained. (W. Raine.) 



334a. Western Goshawk. 



Accipiter artricapillus striatulus Ridgw. 1885. 



Tolerably common throughout British Columbia. More abun- 

 dant west of the Coast range. (Fannin.) One seen at Sooke, Van- 

 couver island, August 2nd, 1893. On April loth, 1903, found a 

 pair in a cotton- wood tree at Penticton, B.C. Nest was a bundle of 

 sticks without lining. Shot both birds. Found an egg in the 

 oviduct of the female, fully formed and shell pale blue. (Spread-
