*" ODOCNTOPHORIDAE (Bob-whites). 
The Bob-whites are known particularly as destroyers of weed 
seed, but during the summer months they capture large numbers of 
chinch bugs, grasshoppers, and various kinds of beetles. They are 
among the most valuable birds on the farm. It is estimated that 
they consume annually 1,340 tons of weed seed in Virginia and Cali- 
fornia. They also eat grain, but this is unharvested grain and 
hence of little value. Bob-whites have been protected by law 
largely because they are game birds. Even with the restriction 
of hunting they are frequently very much reduced in numbers. 
Man and cold, snowy weather are among their principal enemies.
