Cooper's Hawk {Accipiter cooperi). — This and the following species are the real 

 culprits among the Hawks; for their sins all the members of the family have been 

 made to suffer. Compared with the mouse-eating species of the genus (Buteo) 

 they are long, slim birds (see plate), which, as a rule, never scream nor soar, but 

 lurk quietly in ambush as becomes true hunters. Comparison of the appended 

 tables with those giving the food of the so-called Chicken Hawks will readily show 

 how this name has in truth been misapplied. 



The question is, how are we to distinguish these bird-killing Hawks from those 

 which should be preserved. It is a difficult matter. Probably the only safe way to 

 give justice to whom justice is due is to kill only the Hawks we actually see taking 

 our chickens, and not murder indiscriminately every member of the Hawk family.

 to much extent on poultry but lives chiefly on small birds.
