PREPARER'S COMMENTS 



The sudden complete loss of the eastern pop- 

 ulations of the American peregrine and continu- 

 ing decline of most other populations throughout 

 the remainder of its extensive range, attest to its 

 susceptibility to reproductive failure resulting 

 from chlorinated hydrocarbon pesticide pollution 

 of its food chain. Since the subspecies is practically 

 nonmigratory and since most of its range is within 

 the United States and Canada, correction of the 

 chemical poisoning problem by reducing use of 

 the most hazardous pesticides should be relatively 

 easy compared with the Arctic Peregrine, which 

 migrates to Latin American countries where 

 pesticide use is generally excessive. 



The American peregrine management program 

 is fortunate in having an unusual amount of will- 

 ing, expert private citizen volunteer help, particu- 

 larly among active or former falconers. It gives 

 those persons with keen interest and expertise in 

 handling falcons a chance to work with their 

 favorite species as they would otherwise be un- 

 able to do under present regulations governing fal- 

 conry. The unusually large number of authorities 

 and pertinent literature references, and the fact 

 that there are now four Recovery Teams devoted 

 to the American peregrine (more than for any 

 other endangered species) shows the relatively 

 great interest in it and bodes well for its recovery 

 if the all important problem of chemical pollution 

 can be solved in time.— John A. Aldrich
