BLUE GROSBEAK S FOOD ITEMIZED. 



85 



Among the important insect pests eaten by the blue grosbeak are 

 grasshoppers, weevils, the purslane sphinx, and the cotton cutworm. 

 The species deserves protection for its destruction of grasshoppers 

 alone, and when its food habits are considered in their entirety the 

 showing unquestionably is greatly in favor of the bird.
