Bylot Island is a Migratory Bird Sanctuary located adjacent to the northern tip of Baffin Island. It is 25 kilometres (16 miles) north of Pond Inlet, across Eclipse Sound. Covered with mountains, ice fields, steep cliffs, snowfields and glaciers, it provides nesting habitat for large numbers of thick-billed murres and black-legged kittiwakes. The marine waters off the island provide rich foraging for these seabirds. The southwest corner of Bylot Island consists of moist lowland tundra that is ideal nesting habitat for songbirds, shorebirds and waterfowl. Bylot Island has the largest breeding colony of greater snow geese in the Canadian High Arctic. A total of 74 unique species of arctic birds thrive on this island.
