NO. 2 BIRDS OF ALASKA AND SIBERIA — HERSEY 2/ 



feathers about the neck and upper breast and much difficulty was 

 experienced in making good skins. Up to September 8, when I sailed 

 for Seattle, no birds were seen with white appearing in their plumage. 



LAGOPUS RUPESTRIS RUPESTRIS 



Rock Ptarmigan 



First seen at Cape Lisburne where a specimen was taken. Early 

 in September the natives about Nome occasionally brought a few 

 Rock Ptarmigan into town, with larger bags of Willow, and offered 

 them for sale. All those seen at this time showed considerable white 

 among the feathers of the back and head. 



LAGOPUS RUPESTRIS NELSONI 



Nelson's Ptarmigan 



Two specimens, both males, were secured at Unalaska. 



ARCHIBUTEO LAGOPUS SANCTI-JOHANNIS 



Rough-legged Hawk 



At Unalaska a pair were found nesting on the face of a cliff. One 

 of the parents was secured. It was a dark colored bird and does not 

 appear to differ greatly from specimens from various parts of the 

 United States. 



HALIiEETUS LEUCOCEPHALUS ALASCANUS 



Northern Bald Eagle 



Eagles are abundant at Unalaska and even more so at Ketchikan. 

 At the latter place ten were counted in sight at one time and about 

 an hour later six were seen perched in one tree. They were exceed- 

 ingly tame and allowed me to walk under them as they sat about in 

 the tree tops. 



FALCO RUSTICOLUS RUSTICOLUS 



Gray Gyrfalcon 



About Deering are several high cliff's and here were seen five 

 Gyrfalcons. Two birds, an adult and young, sitting together on a 

 rocky projection, were shot. The adult was secured, but the young 

 bird remained on the ledge and was inaccessible. 



I was told that these hawks were quite plentiful in late fall and 

 early winter, and were known to the residents as Ptarmigan Hawks.
