"inter in the neighbourhood of springs, lakes, or large 
breams, in flocks of sixty or eighty. They are easily 
'^ptured by small snares formed of sinews of the deer 
kibe. They are very abundant on the subalpine regions 
°f the Rocky Mountains, in latitude 52° K. longitude 
*15° \V. They are still more numerous in the moan- 
vinous districts of the river Columbia, in lat. 48° N. 
*°ng. 118 W. 
“ This species is rare on the mountains of the north- 
"’est coast. Mr Douglas captured some in April 1825, 
? '4d several more during the winters of 1820 and 1827. 
^he birds from the last named locality appeared larger, 
"ith the general colours more distinct, and a broader 
"larking of white at the extremity of the tail. A few 
s ®asons ago Mr Sabine received specimens of this kind, 
through "the Hudson’s Bay Company, which were 
opposed to have been obtained among the mountains 
"ear the sources of the river Athabasca. 
“ The third species is named the smaller pheasant-tailed 
I’m use, ( Tetrao urophasianellus ,) a beautiful bird, 
"early allied to the pin-tailed grouse of Latham ( Tetrao 
Masianellus.) The general colour is pale brown, richly 
’erred and blotched with black, particularly on the 
Wk and scapulars, where the black forms the prevailing 
tort ion of the plumage. The wing-coverts are marked 
"ith subrounded pale spots, and the outer webs of the 
Primary quill-feathers are also marked with many almost 
"olourless spots of a rounded or oblong figure. The 
s <i.\cs resemble each other in their plumage. The tail 
°f the male is more fully developed, and his dimensions 
"Sceed those of the female. 
“ The flight of this species is swift, steady, and almost 
"oisidess. Their habits approach closely to those of 
tl ‘e large species first described. They inhabit the 
""me country, form their nests after the same fashion, 
""d, in similar situations, subsist on the same food, and, 
Produce their young at the same season. The number 
(, f cgcr S varies” from eleven to fifteen. Of these the 
c °lour is light ash, and their size does not much exceed
