     and around Grand Manan Island, New Brunswick, but most colonies are relatively 
     
     inaccesible. 0n the Bird Rocks north of the Magdalen Islands, Gannets and 
     
     Thick-billed and Common Murres nest in large numbers, but the colonies are 
     
     quite inaccesible. 
     
    
   
   
    
     In order to see enormous concentrations of hundreds of thousands of birds 
     
     one must go to NewaundIand. At Cape Saint Mary's, at Witless Bay, on 
     
     Baccalieu and Funk Islands, seabirds in tremendous abundance carry on the 
     
     squabbles and cares of their urban life. Cape Saint Mary's and Nitless 
     
     Bay are provincial sanctuaries, and visitors are offered guided t0urs. 
     
    
   
   
    
     The habit of nesting on high cliff ledges or isolated islands has served 
     
     seabirds well over the centuries in protecting them from land predators. 
     
    

    
     But nesting on islands does not protect them from oilspills, pesticides and 
     
     poaching; Nor can it eliminate direct disturbance of humans (and their pets) 
     
     at the breeding colonies. If one approaches a colony too close adult birds 
     
    
   
   
    
     leave and their eggs and young are vunerable to gull and crow predation, with 
     
     sometimes disastrous results. 
     
    
   
   
    
     The seabird sanctuaries I have mentioned in this article are all carefully 
     
     managed so that the thousands of visitors each year cause little or no 
     
     disturbance. But there are hundreds of other colonies where no direct pro- 
     
     tection is provided (and this includes colonies on Prince Edward Island). 
     
     All visitors must become informed as to which colonies are vunerable to‘ 
     
     predation‘to avoid distrubance.
