SECTION XV. 



2d Order — Warblers : (Passeres.) 



§279. Warblers are small birds with straight bills 

 and slender feet, which are not webbed. 



§ 280. Many Warblers are accused of destroying cher- 

 ries, corn, wheat, and rice ; but the good which they do, far 

 outweighs the injury. This is evident, if we consider that 

 a single pair of Warblers with their young, consume in one 

 day about fifty grub-worms, caterpillars, or other insects, 

 during the months of March, April, May, and June. 



§281. If we consider also, that at least fifty millions 

 of Warblers dwell during the summer in the United 

 States, we can readily calculate how many thousand 

 millions of insects are devoured by them ; which, if they 

 were left alone, would entirely destroy our orchards, 

 gardens, fields, and forests, and produce, perhaps, famine 

 and pestilence. 



$ 282. Hence to shoot, or otherwise destroy birds, for 

 mere sport, in the spring and summer, when they are la- 

 boring for our benefit and rearing their young, is doing an 

 injury, not only to the farmer, but to the whole community.
