on trend of northern gannets (Sula bassana) is correlated with warming surface water conditions and increased mackerel (Scomber scombrus) availability. On a decadal scale, a major dietary change of breeding gannets from migratory warm-water pelagic fish and squids to cold-water fish is associated with cold-water perturbations in the north-west Atlantic during the 1990s. Cold-water influences appear to have inhibited migratory pelagic fish and squid from moving into the region in recent years, causing a major shift in pelagic food webs on the Newfoundland Shelf. Such findings imply that slight changes in oceanographic conditions, possibly associated with climate warming, could have large-scale and pervasive eVects on seabird distributions, feeding ecology, reproductive success, and populations.
