Falco peregrinus anatum (Bonap.) Blasius. 1862. 



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 

 from European specimens. {Arctic Manual.) Frequently observed 

 in the vicinity of Ivigtut. {Hagerup.) On Marble Island and at 

 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- 

 loops, B.C. It is not a rare bird west of the Coast Range and is 

 a resident on Vancouver Island. Apparently common throughout 

 Alaska and breeding.

Yamaska Mountain, at Abbottsford, about 40 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
