land, which he suggests may possibly have been a migrant or 

 vagrant. Likewise, the duck hawks reported by Captain Ammann 

 and Lieutenant Nelson on Kiska (Clark 1945, p. 36) would have 

 to be migrants or vagrants if we are to retain the subspecific 

 status of these forms. There is, of course, the possibility that 

 these birds were wanderers from Siberia (F. p. calidus). 



Falco peregrinus pealei 



Attu: Ah'-ghu-lich 



Atka: Ah'-ghu-lich 



Commander Islands: Agulekh (Stejneger) 



Russian, Commander Islands: Tschornij Jastrip, black hawk (Stejneger) 



The Aleuts of the Commander Islands speak the language of 

 the Aleutian Islands, and, evidently, the name for this falcon 

 is the same in all dialects. 



It is pretty well established that the nesting birds of the 

 Aleutian chain are pealei, and that this form also nests in the 

 Commander Islands. Probably the same form occupies the Alaska 

 Peninsula and adjacent island groups. However, there is a speci- 

 men of F. p. anatum recorded by Friedmann from Kodiak Island, 

 and we did not collect specimens of F. p. pealei east of the Aleutian 

 chain. 



We found this falcon to be common throughout the Aleutians. 

 It nests on nearly all the islands, usually on high inaccessible 

 ledges. It is a resident breeding bird and also winters in the 

 Aleutians. 



As would be expected, the peregrine falcon feeds chiefly on 

 birds. Casual observations revealed that the least auklet and 

 the crested auklet are taken — one falcon was seen carrying a 

 crested auklet. It has been reported as capturing ptarmigan and 

 shorebirds, but it is believed that sea birds furnish a large portion 

 of its food. 



Falco columbarius: Pigeon Hawk 

 Falco columbarius bendirei 



Friedmann (1935) records a number of specimens of bendirei 

 from Kodiak Island, though, as he points out, Peters states in his 

 check-list of the birds of the world that suckleyi is the breeding 

 bird of Kodiak Island. The 1931 A.O.U. Check-List considers 

 the Kodiak birds to be bendirei. Two specimens were obtained 

 from Kodiak by Gabrielson, August 8, 1945. 



Osgood (1904) records specimens from the Nogheling and 

 Chulitna Rivers, Nushagak Village, and Aleknagik Lake, and 

 he observed others on the Kakhtul and Nushagak Rivers. He also
