HAB. Plains of the United States, from eastern slope of Rocky Mountains, in Montana,

 Wisconsin, southern Michigan, and northern Illinois, 



SUBSP. CHAB. Differing from P. phasianellus columbianus in rather lighter and much 

 more ochi aceous coloration above, with the black bars narrower and less regular, and hav-

In the Bulletin of the Nutlall Ornithological Club for October, 1882, p. 233, Mr. Brewster 

 alludes to differences between specimens of the Sharp-tailed Grouse from Fort Walla 

 Walla, Washington, and others from eastern localities, but concludes that the differ- 

 ences noted "probably have only a local significance." This was formerly my opinion also; 

 but many additional specimens subsequently received at the National Museum show con- 

 clusively that two very different styles of this bird inhabit the regions west and east of the 

 Rocky Mountains, respectively. P. phasianellus columbianus is represented in the collec- 

 tion by specimens from Washington, Oregon, northern California, and Nevada; and P. 

 phasianellus campestris by examples from Montana (east of the mountains), eastern 

 Wyoming and Colorado, Nebraska, Dakota, and Illinois. 



P. phasianellus campestris is the form described and figured by Audubon (B. Am. v, p. 

 112, pi. 298), under the name Tetrao phasianellus. 



This species, so much like the Prairie Chicken in its appear- 

 ance and habits as to be quite generally confounded with it, is 

 apparently confined to the northern portion of the State, where 

 it seems to be of rather uncommon occurrence, at the present 

 time at least. Mr. Nelson (p. 121 of his list) says : 



"If this species now occurs it is extremely rare. Mr. Kennicott 

 notes it as 'not uncommon formerly.' At present it is re- 

 stricted to the northwestern portion of the State. The last 

 record of its occurrence in this vicinity is furnished by my friend 

 Mr. T. H. Douglas, who informs me that in the fall of 18G3 or 

 1864, while two gentlemen were shooting prairie chickens near 

 Waukegan, they found and secured a covey of these birds, num- 

 bering fourteen individuals. These had, in all probability, been 

 raised in the immediate vicinity."
