This wildlife area, proposed by the community of Clyde River, includes important summer habitat for a population of bowhead whales that has been assessed as threatened in Canada. The bowhead is a large and powerful marine mammal that can break through ice over 20 centimetres (8 in.) thick with the crown of its head. It navigates and communicates under extensive ice fields using its sophisticated acoustic sensory skills. While some of the bowhead population moves westward through Lancaster Sound in late June and early July, others, mainly adults and large adolescents, remain off the east coast of Baffin Island for the summer and fall.
