356. Duck Hawk. 
Falco peregrinus anatum (BONAP.) BLASIUS. 1862. 
A common species in Greenland. (Wzinge.) 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 
bn ee Walker ol thes Hox  ReY Sy ab Port Kennedy, lat. 72°" N., 
are specifically indistinguishable from European specimens. (Arct. 
Man.) Frequently observed in the vicinity of Ivigtut. (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. (A. 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. (Atkinson.) 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. (fF vggins.) So far this is the only 
species of peregrine I have been able to secure at Comox. I expected 
Pealez to be the common form on Vancouver island. (Brooks.)
