THE OREGON NATURALIST. 



^gialitis moni;ola 

 MONGOLIAN PLOVER. 



Two specimens obtained August 9, 1892. 

 No others seen and nothing learnt of their 

 habits. 



Arenaria melanacephala 

 BLACK TURNSTONE. 



A breeding resident frequenting rocky 

 beaches, particularly on the outlying 

 islands. No nests were obtained but 

 specimens were obtained all through the 

 summer months. 



Haematopus bachmani 

 BLACK OYSTER CATCHER 



Resident on the island throughout the 

 year and undoubtedly breeds. Although 

 the writer was very anxious to obtain an 

 egg of this species he was unable to do 

 so. An egg was brought by a native who 

 represented it to be an egg of this bird; 

 upon investigation it was found to be in 

 an advanced stage of incubation and 

 contained a well developed yow tern. 

 Lagopus lagopus 

 WILLOW PTARMIGAN 



The willow ptarmigan or snow grouse 

 as they are commonly called, are found in 

 all parts of the island, but it is in winter 

 when they gather in large bands that they 

 are must noticable, particularly on account 

 of the avifauna being so limited at that 

 season of the year. 



The habits of these birds, particularly 

 their flight reminds the writer greatly of 

 the prairie hen; they have the same habit 

 of all not rising in a band, but always 

 there are a few stragglers that get up 

 after the first or second volley has been 

 fired. In the winter their food consists of 

 the shoots of the willow and the new 

 leaves of the kinnikanic, but in summer 

 they feed largely on berries and insects, 

 chiefly the spider. They nest in the 

 interior of the island and the eggs are laid 

 in May or as late as the first part of June. 

 They lay from ten to fourteen in number. 



Lagopus rupestris 

 ROCK PTARMIGAN. 

 A few of these birds are found on the 

 higher ranges of the island, but no new 

 facts concerning them were learned. 

 Circus hudsonius 

 MARSH HAWK. 

 A summer resident breeding in suitable 

 places in the island and feeding on Arvicola 

 and Spermophile. 



The nest being on the face of high 

 bluffs are nearly always inaccessible. 

 Buteo sLuainsoni 

 SWAINSON'S HAWK 

 A very common summer resident and 

 undoubtedly breeds although no nests were 

 found. 



Archibuteo loiicptts sancti-Johannis 

 AMERICAN ROUGH-LEGGED HAWK 

 Resident during the summer months, 

 breeding in the interior. 



Halicetus leucocephalus 

 BALD EAGLE 

 There are about a dozen pairs of these 

 birds resident on the island but they are 

 not nearly so common as on the mainland 

 where they are in all probability more 

 abundant than anywhere else on the 

 American Continent. 



Faico peregrinus anatum 



DUCK HAWK. 



A common resident throughout the year, 



nesting on high bluffs near to the ocean. 



FaIco sparuerius 



SPARROW HAWK. 



A tolerably common summer resident 



PaiiiHcn kaliaetus caro/ittensis 

 AMERICAN OSPREY 

 One seen May 23, 1894.

HAWK OWL. 

 The light phase of the hawk owl was 

 met with throughout the year and un- 

 doubtedly is a breeding resident though no 

 nests were found. In summer their food 

 consists of fi'^'ld mice (Afvko/a) and in
