Geese, sea ducks and shorebirds stage in coastal areas during spring and fall. Harp seals and hooded seals whelp on the offshore ice around the Magdalen Islands in early spring. Both species then migrate north, following the retreating ice, with the harp seals swimming more than 3200 km to reach their Arctic summering grounds. Grey seals give birth on the newly formed ice in eastern Northumberland Strait and along western Cape Breton Island. Following the breakup of the ice the greys wander but generally remain in the Maritimes, while harbour seals are common residents of the region.
Cetaceans are generally uncommon except along the edges of the region where deeper waters are found.
This region is not yet represented in the national marine conservation areas system. Selection of the preferred site for consideration as a possible national marine conservation area is the next step. Information last updated May 30, 2001.
