128 GAME BIRDS OF NORTH AMERICA. 
on trees. I think, however, this is a common habit of 
all Sharp-tailed Grouse if they happen to be in a country 
where trees abound, and it is a very usual occurrence in 
winter, or early in the morning during the autumn, to 
see numbers of Grouse standing or sitting upon the 
branches. When flushed they always cackle as they rise, 
and fly swiftly in a straight line, alternately sailing along 
and then flapping the wings with a few quick, short 
strokes. They are able to go long distances without 
stopping, but, as a rule, when not much hunted, they 
alight after making a short flight. As the country be- 
comes settled this Grouse is more seldom met with, as 
it retires to the wilder portions of the land, for, unlike 
the Pinnated Grouse, it is a bird of the wilderness and 
shuns man’s habitations.
