A common species in Greenland. (Herluf Winge.) Said to 
breed generally throughout Greenland, certainly up to Lat. 
69° N.and in many of the lands to the westward of Baffin 
Bay. Examples obtained by Dr. Walker of the “ Fox” R.Y.S., 
at Port Kennedy, Lat. 72° N., are specifically indistinguishable

York Factory, Hudson Bay, September, 1885. (Dr. R. Bell.) 
This species is rare in Newfoundland and Nova Scotia as a mig- 
rant. Reported to breed in New Brunswick by Chamberlain and 
known to breed in Quebec and Ontario: Probably breeds in 
northern Manitoba, but is rare on the prairies. Only three speci- 
mens were seen by Mr. Spreadborough at Indian Head, Assa., in 
the spring of 1892. It is commonly met with in the wooded 
country north of Lat. 52° in the autumn. It is rare in the moun- 
tains as no specimens were ever seen between Calgary and Kam-

a resident on Vancouver Island. Apparently common throughout 
Alaska and breeding.

Yamaska Mountain, at Abbottsford, about 4o miles east of 
Montreal, has been a breeding place for this species for many 
years. Mr. Fisk reports that a pair of these hawks had a 
nest on the west side of the mountain, and he has observed 
this species there every year for forty years past. He took two 
eggs of the duck hawk in April, 1891, there, from under a rocky 
ledge ; no material was used for the nest, only a slight hollow 
scratched out by the hawks under a shelving rock. (Wintle.) A pair
