Bob-White 139 
typical form of one of these only is found in Colorado. It is possible 
that the Texan subspecies (C. v. texanus) may reach south-east Colorado. 
It is distinguished by its slightly smaller size—wing 4-4, by its 
heavier brown barring below, and its less reddish tone above. 
Bob-white Colinus virginianus.

Distribution.—Eastern North America from Maine and southern 
Ontario to northern Florida, westwards to south Dakota and eastern 
Colorado. 
The Bob-white did not extend much beyond central Kansas in the 
middle of last century, but with the spread of settlement it has extended 
its range westwards over the prairies to the eastern portion of Colorado ; 
while at the same time it has been introduced by human agency all 
along the foothills-country from Pueblo to Fort Collins. It is also to 
be found in Estes Park and Wet Mountain Valley, at La Junta and near 
Grand Junction, where it has doubtless been introduced as well. 
Bob-whites are not uncommon in the south-east.corner of the State 
(Warren), but whether these are the eastern or Texan form, is uncertain. 
It is probably a resident throughout its range. 
Habits.—The Bob-whites prefer fairly open, cultivated 
lands, meadows and pastures, with patches of bush and 
briars where they can take shelter. They are generally 
to be found in small coveys or parties, which do not 
range very far from where they were raised. In the 
spring the coveys break up into pairs. The Bob-white, 
which is often called the Quail or Partridge in the east,
