Île aux Canes Migratory Bird Sanctuary

The Ile aux Canes Migratory Bird Sanctuary (MBS) is located off the northeastern coast of Newfoundland and Labrador. It allows eiders to nest and raise their chicks.

Importance of the sanctuary: migratory birds and other wildlife

Located in the District of Strait of Belle Isle, off the northeastern coast of Newfoundland, Île aux Canes Migratory Bird Sanctuary is a 150-hectare protected area locally known as Green Island. Along with nearby Shepherd Island, this sanctuary is one of the largest breeding sites for the common eider in Newfoundland. In fact, these two areas are the only sites where the numbers of breeding common eider have increased in recent years, although predation by fox and polar bear has recently become a problem and may be bringing population numbers down.

Common eiders are known to prefer isolated locations for their nesting colonies, which is limiting for their geographic distribution. The number of nests in this protected area increased from 12 in 1975 to 350 in 1988, and again to 1291 in 2001. The sanctuary’s gently sloping bedrock “ramps” provide easy access for the flightless young birds and the intertidal and subtidal zones are ideal feeding habitat for these birds as they support an abundance of marine invertebrates, including blue mussels, periwinkles, whelks and amphipods. The surrounding shoals (shallow waters) help to diminish the waves, making it easier for the young birds to feed. According to the Protection Plan for Green and Shepherd Islands (1988), the total number of common eider nests that these islands can support is estimated to be 5000.

Did you know?

Common eiders dive down under the water to collect molluscs and crustaceans. They particularly favour mussels, which they swallow whole, grinding up the shell in their gizzard to later expel the fragments.

Landscape

The Île aux Canes Migratory Bird Sanctuary, established in 1991, includes Green Island as well as the surrounding waters, small inlets and rocks. While the southeast side of the island is raised, the rest is low-lying and gently slopes towards the sea. The low-lying portion makes up 60% of the total area and has an overburden of rich organic matter. The major species of vegetation on the island are marsh cordgrass and cow-parsnip, with the higher portion of the island supporting mostly low-growing ericaceous shrubs (commonly known as the heath or heather family) such as crowberry that tolerate acidic soil. The waters surrounding the island are shallow, usually less than five metres, with many shoals, submerged rocks and islets.

Access to the sanctuary

Migratory Bird Sanctuaries, such as Île aux Canes, are established across the country to protect migratory birds during critical periods of their life cycle. Whether these areas are used for feeding, resting or nesting, they play an important role in the survival of many species. Access to each migratory bird sanctuary varies by site and is at the discretion of the landowner and land manager. Please ensure that you are aware of how you can help protect this sanctuary and please read the restrictions, including those on firearms and hunting, which are in place to conserve the wildlife that call it home. Dogs and cats must not be allowed to run at large inside Migratory Bird Sanctuaries.
