A LIST OF THE MAMMALS 87 



Rocky Mountain Nuthatch (Sitta carolinensis nelsoni). Seen 

 November 8 in the East Short Pines, by Saunders. 



Red-bellied Nuthatch (Sitta canadensis). A common resident in 

 the pines of the buttes. 



Long-tailed Chickadee (Penthestes articapillus septentrionalis) . 

 Breeds abundantly in the forests of the buttes. Common 

 later in the woods elsewhere. 



Olive-backed Thrush (Hylocichla ustulata swainsoni). Frequent 

 migrant. Taken in September, 1912, near Camp Crook. 



Willow Thrush (Hylocichla fuscescens salicicola). Not uncom- 

 mon along the Little Missouri, August 27-September 3. 



Robin (Planesticus migratorius migratorius). Seen seyeral times 



in August, 1910. 

 Western Robin (Planesticus migratorius propinquis). Nested 



quite plentifully in the Short Pines in 1911. The two vari- 



eites of robins differ most noticeably in regard to white on 



the tail. The eastern robin has some, and the western has 



none. 

 Bluebird (Sialia sialis). Common breeder in the pines of the 



higher buttes. 

 Mountain Bluebird (Sialia cnrnicoides). A brood was seen in the 



Short Pine Hills. Grinnell also reports seeing a brood of 



young there in 1874. 



V. A PRELIMINARY LIST OF MAMMALS OF HARDING 



COUNTY. 



Compiled by S. S. Visher. 



[Elk (Cer-cus canadensis). Formerly were doubtless abund- 

 ant. The last were killed in 1879 when a large crew cut trees for 

 the N. P. R. R. in the Long Pines. We found two skulls in the 

 Cave Hills, one of which was well preserved. Some of the older 

 settlers have fine antlers.] 



Western \\~hitetailed Deer (Odocoileus virginicmus macron- 

 rus). Until quite recently this deer was fairly plentiful in the 

 forest reserves. In 1910 we saw deer or certain evidences in each. 

 During the winter of 1910 over thirty were killed in Slim Buttes. 

 It is believed that thev are now nearlv exterminated.
