Highlights
Seabirds nesting in the migratory bird sanctuaries of the North Shore are surveyed every five years. Their status is considered “moderate” due to trends observed in five indicator species: the Common Murre and Razorbill are doing very well, the reduced number of Atlantic puffins is increasing, the status of tiny Caspian Tern population remains precarious despite recent growth, and the decline of the American Herring Gull continues. The abundance of food resources, the presence of predators, and human disturbance are key factors at play.
