289 Bob-white. Colinus virginianus. 



Range. United States east of North Dakota and Texas and from the southern 

 British Provinces to the Gulf coast. 



A celebrated "game bird" which has been hunted so 

 assiduously in New England that it is upon the verge of 

 extermination, and the covers have to be continually 

 replenished with birds trapped in the south and west. 

 They frequent open fields, which have a luxuriant 

 growth of weeds, or grain fields in the fall. Their nests 

 are built along the roadsides, or beside stonewalls or 

 any place affording satisfactory shelter. The nest is 

 made of dried grasses and is arched over with grass or 

 [White]. overhanging leaves so as to conceal the eggs. They lay 



from ten to twentv pure white eggs, which are very fre- 

 quently nest stained when found. Size 1.20 x .95. Often two or three broods 

 are raised in a season, but frequently one or more broods are destroyed by rainy 

 weather.

Range. This sub-species, which is found in the southern half of Florida, is 

 very much darker than the northern Bob-white, and is numerously barred below

289b. Texan Bob-white. Colinus virginianus texanus. 



Range. Texas; casually north to Kansas. A grayer variety of the Bob-white.
