141. Glaucidium gnoma pinicola Nelson 



Rocky Mountain Pygmy Owl 



A permanent resident of the mountains in the western haK of th.e state. 

 There is one record in the eastern half, and the bird may occur rarely througli- 

 out the state. It probably occurs in all the mountain ranges, but it has not been 

 reported from the more eastern ones. In most places it is reported as rare, but 

 I believe that it is merel}^ overlooked, and that on the whole it is the commonest 

 owl in the mountains. The easternmost records of this owl are as follows : 

 Tongue River, one bird, January 4, 1895 (Cameron, 1907, p. 269) ; Gold Run, 

 April 14, 1882 (Williams, 1883, p. 59) ; Gallatin County (Saunders, 1911a, p. 

 37) ; and Teton, and Lewis and Clark counties (Saunders, 1914a, p. 133). 



The only definite knowledge of the nesting of this species in the state is 

 the record of a nest and newly hatched young found on Bridger Creek, Gallatin 

 County, by Mr. Thomas in June, 1909 (Saunders, 1911a, p. 37). 



142. Coccyzus erythrophthalmus (Wilson) 



Black-billed Cuckoo 

 A summer resident of eastern Montana. On the Upper Missouri as far as 

 Wolf Point (Grinnell, 1876, p. 648). A cuckoo seen in the Yellowstone Valley 

 was probably of this species (Allen, 1874, p. 63). Pryor's Fork of the Yellow- 

 stone, also breeding on Little Horn River and at Fort Custer, June 25, 1885 

 (Bendire, 1895, pp. 27 and 30). A rare summer resident of Custer and Dawson
