356. Duck Hawk. 



Falco peregrinus anatum (Bonap.) Blasius. 1862. 



A common species in Greenland. (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. (Arct. 

 Man.) Frequently observed in the vicinity of I vigtut. (Hagerup.) 

 On Marble island and at York Factory, Hudson bay, September, 

 1885. (Dr. R. Bell.) One seen on the Barren Grounds below Cape 

 Eskimo, Hudson bay, August 5th, 1901. Recorded by Murray 

 from Trout lake and Severn House and by Clarke from Fort Churchill. 

 (Preble.) More common than the gyrfalcon in the Hudson bay and 

 strait region. (.4. P. Low.) 



This species is rare in Newfoundland and Nova Scotia. 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 specimens were seen by Mr. 

 Spreadborough at Indian Head, Sask., 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 mountains as no specimens were ever 

 seen between Calgary and Kamloops, 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. 



Rare at Aweme, Man., probably breeds. Arrives about April 

 14th, returns in October and departs towards the end of that month. 

 (Criddle.) A regular migrant in Manitoba. Not seen in 1906 on 

 the western prairie until Tramping lake, Sask., was reached early in 

 August but from there west, about the larger waters, it was seen 

 pursuing ducks. I found it also ruthlessly pursuing avocets and 

 willets. (Atkinso7i.) Seen almost every day between Stewart river 

 and Circle, Alaska, and at many places between Circle and the mouth 

 of the Yukon. (Bishop.) On Popof island, Alaska, a pair of these 

 birds was seen nearly every day. (Figgins.) So far this is the only 

 species of peregrine I have been able to secure at Comox. I expected 

 Pealei to be the common form on Vancouver island. (Brooks.) 



Breeding Notes. — Abundant at Fort Chimo, Ungava bay, nest- 

 ing on cliffs. Eggs obtained May 24th. (Packard.) Said to breed
