THE MEXICAN COTTON-BOLL WEEVIL. 



Table LXVI. — Schedule of stomach examinations of birds which had eaten boll weevils. 



It will be noticed that the largest numbers of boll weevils were 

 eaten during the months of July, August, and September, and also 

 that a considerable number are consumed during the hibernating 

 season. The most important birds are those that capture the boll 

 weevil during the winter. According to this table these are the 

 three species of blackbirds, two meadowlarks, six species of native 

 sparrows, the pipit, the three species of wrens, and the two species 

 of titmice. It will be noted that only one of the 108 quail stomachs 

 examined showed remains of the boll weevil.
