A bob-white kept in captivity ate 1350 flies in one

Mr. E. H. Baynes, in his "Wild Bird Guests," 

 writes : — 



The pair of phcebes on our piazza, with two pairs of tree 

 swallows which nest in boxes in the garden, and a pair of 

 barn swallows in the barn, keep our house practically free 

 from flies and mosquitoes all summer long.
