From the author: The Gannet Islands contain the single most important seabird colony in Labrador, both in terms of numbers and species diversity. In 1992, we discovered arctic foxes (Alopex lagopus) on these islands during the breeding season. Of five islands examined, two had resident foxes (in one case breeding), two had been visited by foxes earlier in the season, and one had no foxes and had not been visited. A comparison of these islands in 1992 and with our detailed studies from the early 1980s, revealed the effect that foxes had had on seabirds. On islands with foxes, Razorbills (Alca torda), Common Murres (Uria aalge), and Thick-billed Murres (U. lomvia) had ceased breeding. Atlantic Puffins (Fratercula arctica) continued to attempt to breed, but fox predation on adult birds and eggs was intense and breeding success low. On islands visited by foxes earlier in the season, the number of breeding Razorbills was reduced, and breeding by Common Murres was delayed by 2-3 weeks.
