rows, warblers and meadow-larks); 2, quail; 1, bullfrogs; 3, mice 

 and insects ; 2, hair and other remains of small quadrupeds.

 single farm-yard, twelve of them in one day. 



It is conceded by practically every ornithologist that the Cooper's 

 Hawk may well be reduced in numbers, if not exterminated, with 

 profit, but it is of the greatest importance that those who attempt to 

 reduce its numbers be able to distinguish the nests, eggs and young 

 of this species readily in order that innocent and beneficial hawks 

 may not suffer with the guilty.
