are not necessarily equal in importance. Much of its damage to crops 
and poultry can be prevented, while the bird's services in the control 
of insect pests can ill be spared. At the same time no policy can be 
recommended which would allow the crow to become so numerous 
that its shortcomings would be greatly accentuated. As the capabili- 
ties of the crow for both good and harm are great, it is believed that 
an extermination of the species would have ultimate consequence's no 
less serious than an overabundance. 
Inasmuch as this investigation aimed at reaching general conclu- 
sions respecting the status of the crow, in order that our attitude 
toward the bird might be based on sound economic principles, it may 
be said that the laws relating to it, at present in force in most States, 
are altogether satisfactory. It is well that no protection be afforded 
the bird and that permission be granted for shooting it when it is 
actually found doing damage. Bounties can not be recommended, 
neither can a campaign of wholesale destruction where complete ex- 
termination is the object sought. However, a reasonable reduction 
of numbers is justifiable in areas where there is an overabundance of 
the birds. The attitude of the individual farmer toward the crow 
should be one of toleration when no serious losses are suffered, rather 
than one of uncompromising antagonism resulting in the unwar- 
ranted destruction of these birds which at times are most valuable 
aids to man.
