78 OKUISB OF STEAMER CORWIN IN THE ARCTIC OOEAK. 



FALCO PEREGRINUS PEALEI Ridgw. 



(GO.) Peale's Falcon. 



Alonpf the Aleutian Islands Dall fDiind this bird rather common and nesting at various points 

 In his "List of Birds West of Oiitialaska," lie heids the list with this species, having it identified 

 as Fnlco gyrfalco. Mr. Ridgway informs me that this bird, of which ho has examined the specimen 

 obtained by Dall and upon which the erroneous identification was based, is in reality a typical 

 Falco pealei. On September 23, 1.S81, as the Oorwin api)roached Ounalaska front the north six or 

 seven of these birds were seen, one after the other, approaching from the east, and, after a 

 circuit about the vessel, frequently coming within thirty or forty yards, they would make off to the 

 west. At this time the island was nearly twenty miles distant. This was the only time that the 

 bird was observed during the ten days spent at Ouiuilaska. It is unknown north of the Aleutian 

 Islands, although it undoubtedly extends farther north along the Alaskan shore. 



.aSSALON COLUMBARIUS (Linn.) Kaup. 



(67.) The Pigeon Hawk. 



This well-kuown Hawk occurs along the entire Alaskan coast north beyond the shores of Kotze- 

 bue Sound. Across Bering Sea it has been taken at Plover Bay and several other points on that 

 coast. Of the woodland birds of prey this is one of the most common species to visit the barren 

 coast region, and may be looked for as a rather frequent and regular visitant along the shores of 

 Norton Sound, Baring Strait, and Kotzebue Sound in spring, summer, and autumn. A skin was 

 brought on board the Corwin from one of the islands in BeriTig Strait in the summer of 1881. 

 Although numerous in the portions of this region named, it is yet unknown from tlie Aleutian and 

 Seal Islands, the bleak, rugged character of their shores probably proving unattractive to this small 

 but bold Falcon. 



PANDION HALI.3:TUS CAROLINENSIS (Gm.) Ridgw. 



(68.) The American Fish-Hawk. 



In the interior the Fish-Hawk is a not very uncommon bird as far north as the wooded country 

 extends ; thence it occasionally visits the shores of Bering Sea. Two were seen the last of May at 

 the Yukon mouth in 1879, and two specimens were brought me from the head of Norton Sound 

 during the summer of 1878. These records include all the information I possess regarding this 

 bird on the coasts herein treated. Whether it is found on the Siberian shore or not in these high 

 latitudes I have no information, although its presence to the south in the Kurile Islands and 

 southward render it probable that it does. 



CIRCUS HUDSONIUS (Linn.) Vleill. 



(69.) The Maesh Hawk. 



A common migrant along the Alaskan shore of Bering Sea, occasionally found on the Aleutian 

 Islands and extending its range north beyond Kotzebue Sound. It undoubtedly occurs upon the 

 adjoining coast of Siberia, although I do not possess any record of its having been observed there. 



ACCIPITER FUSCUS (Gmel.) Bp. 



(70.) The Sharp-shinned Hawk. 



Like the Pigeon Hawk, the Sharp-shinned Hawk occurs during the entire summer season, from 

 spring to fall; but, unlike the former, it is of considerable rarity and found, as far as my information 

 goes, only along the Alaskan coast, including the shores of Bering Sea and Kotzebue Sound, but 

 not extending to the islands of this sea nor to the adjoining coast of Siberia.
