[601] BIRDSOFOREGON 



Red-legged Black Duck: 



Anas rubripes rubri-pes Brewster 



THIS NORTHERN AND EASTERN species, which does not come regularly far 

 west of the Mississippi, was reported by Law (1887) from Sauvies Island, 

 Oregon. We have not been able to trace any specimens on which this 

 record was based, and in view of the absence of any other reference to 

 the bird, we are placing it on the hypothetical list. 



Red-bellied Hawk: 



Buteo lineatus elegans Cassin 



THIS BIRD was recorded by Johnson (1880) as occurring in East Portland, 

 Forest Grove, and Salem; and Bendire (1892.) listed eggs from Camp 

 Harney. Other than this we have no record of this species from Oregon 

 and are inclined to doubt the correctness of the identifications. We are 

 placing it in the hypothetical list therefore until further information 

 is available. 



Richardson's Pigeon Hawk: 



Falco columbarius richardsoni Ridgway 



RECORDED by Bendire (1877, 1892.) and Brooks (1896), this species as 

 now understood, is not an Oregon bird, its place on our list having been 

 taken by the Western Pigeon Hawk. 



Northern White-tailed Ptarmigan: 



La go f us leucurus leucurus (Richardson) 



ALL OF the records of this bird in Oregon can be traced back to state- 

 ments of early explorers that it occurred in the Mount Hood and Mount 

 Jefferson regions. So far as we know, it has never been taken in the State. 

 The present southern range of the species is in the Washington Cascades 

 just south of Mount Rainier. We are therefore placing it in the hypo- 

 thetical list. 



Greater Prairie Chicken: 



Tympanuchus cupido americanus (Reichenbach) 



BONAPARTE (182.8) reported the Prairie Chicken from Oregon, and Wood- 

 cock (1902.) published the statement of Ellis F. Hadley that one was 

 killed in October 1892., near Dayton. There is no other record of this 

 bird in the State, and we are placing it in the hypothetical list, as it is 

 almost certainly a case of mistaken identity. Eastern Oregon records of 

 the Prairie Chicken undoubtedly refer to the Columbian Sharp-tailed 

 Grouse.
