     Most people realize that many bird species migrate 
     
    
   
   
    
     south in fall, but have you ever wondered exactly 
     
    
   
   
    
     where birds from Prince Edward Island go? Unfortun— 
     
     ately, the answer is not available for the majority 
     
    
   
   
    
     of the Island's species. To find out it is necessary 
     
    
   
   
    
     6 
     
    
   
   
    
     to identify individual birds by using such techniques ' A; 
     
     as dyes or specially coded leg bands. When a bird 
     
    

    
     wearing a leg band is found, the band (or the number on the band) should be sent to 
     
     the U.S. Fish and Wildlife Service, Washington D.C. with the date of recovery, the 
     
     recovery location, and the present condition of the bird. Because birds do not 
     
    
   
   
    
     recognize political boundaries, the U.S. and Canada work together on this. 
     
    
   
   
    
       
     
    
   
   
    
     In addition to the annual "acer- 
     
     fowl banding program conducted on Prince 
     
     Edward Island by the P.E.I. Fish and Wild- 
     
     life Division there have been several 
     
     other banding programs which have pro- 
     
     vided data on the migration of Island 
     
     birds. It is the results of these pro- 
     
    
   
   
    
     grams that I will present here.
