18 THE FAUNA OF MONTANA TERRITORY. 
the eastern slope of the Rocky Mountains, but not among 
them, though it probably occurs there sparsely. 
Livconw's Fwon (M. Lincolnii). Rather common in 
flocks along the Bitterroot River, migrating in September. 
Arctic Grounp-FIncH (Pipilo detiene). I observed 
specimens which I supposed to be of this species, entirely 
across the Rocky Mountains, and preserved one from each 
side. In habits they resembled the eastern and west coast 
species, and I observed little difference in their notes at that 
season from those of P. Oregonus. I also preserved a nest 
and eges of this ( ?) from along the Missouri River. 
Bosornrk (Dolichonyx oryzivorus). At several points in 
the valley of the Bitterroot River, I heard and saw at a dis- 
tance what I took for the Bobolink, the flight and flying- 
call exactly resembling that bird’s. At Coeur d’Alefie Mis- 
sion I again met with it, but could not get near enough to 
shoot it or determine the species, though they frequented a 
wheat-field for several mornings. I know no bird likely to 
be mistaken for it, and having been found at Fort Bridger, a 
few probably go north to latitude 47° 30’, as they go to 
latitude 54° east of the mountains, according to Richardson. 
The Calamospiza, which is common near Fort Benton, I saw 
no farther west, and its notes and habits are quite different. 
ow Buntine (Molothrus pecoris). I saw this bird only 
ence near Fort Benton, but as it abounds along the Platte 
River and follows trains of wagons, cattle, etc., besides being 
found at Fort Bridger and Sacramento, Cal., I should be 
surprised if it did not occur in the present limits of Wash- 
ington Territory, at least along Snake River, and possibly 
follow emigration as far as the Cascade Mountains. I seeno - 
reason whe it should not also emigrate to the open regions 
north of the Columbia ; and Townsend has it in’ his list/of 
“Oregon” birds (1834). 
D-WINGED BLACKBIRD (Agelaius phoeniceus). Common 
at Cour d'Alene Miot, Fort Colville, and Bitterroot
