TEE HAWKS AND EAGLES 



Falconidae 



This section of the Order Raptores contains a remarkable 

 assemblage of forms, and the wide differences between some 

 of the groups add zest to the study of them. Some are ex-

 species of day-flying birds of prey in North America, there 

 were only four species whose destructiveness so far outweighed 

 their useful services that they deserve to be destroyed. The 

 others are either harmless to man's interests, or else so posi-

 doubt, the careful and thorough investigations made by the 

 Biological Survey and the publication of the results have 

 resulted in the correction of popular errors which if persisted 

 in would have caused enormous losses to the farmers of the

 of those birds, at the rate of fifty cents each. Immediately 

 the work of slaughter began. Many thousand scalps of hawks
