THE FAUNA OF MONTANA TERRITORY. . 81 
A. V. Kautz shot two. It thus seems to pass round to the 
north of that plain, and occasionally to cross the Cascade 
Range, as mentioned by Dr. Suckley in 1853. 
Along the Missouri I often saw small flocks, and noticed 
quite a number of their nests in small trees between Forts 
Pierre and Berthold. I found one sitting June 7th, and 
heard that many build farther south, near Sioux City. 
In the mountains they fed, in August, chiefly on the Ser- 
vice-berry (Amelanchier alnifolia), which, along the Hell 
Gate, attains a size and flavor unequalled by any I have 
seen elsewhere. 
Dove ( Zenaidura Carolinensis). I did not see this bird 
anywhere in the mountains, though I found it above Fort 
Union, on the Missouri. 
Dusky Grouse (Tetrao obscurus). This Grouse was shot 
at the very beginning of pine woods on the east base of the 
Rocky Mountains, and I often killed them afterwards all 
the way to Fort Colville, but none in very good plumage 
up to October. 
FnaxkLIN's Grouse (T. Franklinit). The first specimen 
met with was shot through the head with a pistol ball, by 
Lits L; Rs L. Livingston. It is much smaller than num- 
bers 123 and 124, which were trapped by the Indians near 
Fort Colville, three weeks later. I did not see any alive 
myself, büt was told that in winter they are common south 
to Spokan River, and very stupid, standing by the roadside 
to be shot, having doubtless descended from the mountains, 
Where they were unmolested. They are also common in 
summer near the pass, 5100 feet above the sea, on the Cœur 
d'Aleie Range. 
I now believe that two young specimens, one killed in 
Klickatat Pass, Cascade Mountains, in August 1853, the 
other near Spokan River, in October 1853, and mentioned in 
my Report as T. obscurus, "running through the snow," were 
of this species. In their immature plumage I then supposed 
the red mark over the eye to be merely a character of the
