BIRD BIOGRAPHIES 



are large insects captured and swallowed, but even small 

 birds, in two cases warblers. 



"Despite the fact that the chuck-will's-widow occasion- 

 ally devours small insectivorous birds, it must be reckoned 

 a useful species. It is probable that birds are not de- 

 liberately sought, but that they are taken instinctively, 

 as would be a moth or other large insect coming within 

 reach of that capacious mouth." ^
