Kendall Island Migratory Bird Sanctuary, Migratory bird sanctuary in Northwest Territories, Canada.

Kendall Island Migratory Bird Sanctuary covers 609 km2 of Mackenzie Bay at the northern tip of the Mackenzie River Delta, about 120 km west of Tuktoyaktuk. Its low-lying terrain of shallow channels and extensive mudflats surrounds islands built mostly of muskeg; several hills of sand or glacial till have stayed above water since glaciation.

The sanctuary was established in 1961 to protect nesting colonies of snow geese in this northern region. This designation reflected efforts to safeguard critical stopover points along major bird migration routes.

The area now within the sanctuary is a traditional Inuvialuit whaling site. The Inuvialuit Settlement Region, which contains the sanctuary, is one of five bird sanctuaries in the region. The name Kendall Island refers to the island at the northern tip of the Mackenzie River Delta.

The sanctuary lies on the Beaufort Sea coast, about 120 km west of Tuktoyaktuk and 140 km north of Inuvik, with no road access; reach it by boat or aircraft. The Mackenzie Delta channels freeze in winter, and the bird season runs from May through October. Entry requires a permit from the Canadian Wildlife Service.

The area shares space with two natural gas fields holding substantial energy reserves, an unusual combination of wildlife protection and resource development. This coexistence shows the competing pressures on northern lands.
