Hannah Bay Migratory Bird Sanctuary
Hannah Bay Migratory Bird Sanctuary (MBS) forms the southernmost projection of James Bay. The lands are managed by the Province of Ontario, and the areas below the high-tide mark are managed by the Government of Nunavut. The MBS is located on the east side of the bay and stretches northward from the mouth of the Little Missisicabi River to East Point. The MBS extends 6.4 km west from East Point and includes open water, shoals and tidal mud flats that are part of Nunavut. In addition to the coastal area, the MBS includes sedge marshes, inland fens and spruce forest that stretch eastward to the Ontario-Quebec border. The northern boundary of the MBS is a line due eastward from East Point to the Ontario-Quebec border, while the north bank of the south branch of the Little Missisicabi River forms the southern boundary.
The Hannah Bay MBS is characterized by areas of extensive tidal mud flats and well‑developed sedge marsh interspersed with lakes and streams. The tidal mud flats, which may reach a few kilometres in width, are hard-packed silt and clay; the water in this area is brackish and turbid. Following the flats are sedge-dominated marshes with rush and bulrush on the edges, and occasional pool areas colonized by Potamogeton sp. On higher sites, needlerush and grasses are found, while cattail and mare's tail grow in the numerous shallow ponds. The deeper potholes contain a variety of submergent plants, including Myriophyllum spicatum, Potamogeton sp. Farther inland, extensive wet meadows, freshwater swamps, fens and bogs, and black spruce forest cover the area. Willow species may be found along the banks of streams such as the Little Missisicabi River.
Importance of the Migratory Bird Sanctuary
The funnel-shaped outline of Hudson and James bays causes migrating birds from the Arctic to concentrate at the southern end of James Bay each fall. Extensive tidal flats, coastal marshes and inland fens attract hundreds of thousands of ducks, geese and shorebirds each autumn. The above-noted vegetation zones are common along the southern shore of James Bay, but the coastal sedge marsh zone is considerably wider at the Hannah Bay MBS than along other sections of the shoreline.
The most common fall migrants are Lesser Snow Geese, Canada Geese, Northern Pintails, American Black Ducks, Mallards, Green-winged Teals and White-winged Scoters. Lesser Snow Geese are found in numbers reaching several thousands during the fall and spring migration through the Hannah Bay MBS (see table). In its 1982 Goose Survey, the Ontario Ministry of Natural Resources recorded over 7000 Lesser Snow Geese in the MBS, which constituted one fifth of the total number counted in southern James Bay in the survey. These habitats are essential for waterfowl as feeding grounds to replenish their fat reserves in order to continue their migratory journey.
|Date||Lesser Snow Geese||Canada Geese|
|Oct. 4–6, 1971||35,897||–|
|Oct. 15–18, 1971||64,538||–|
|Sept. 19–22, 1972||14,435||1884|
|Oct. 4–10, 1972||28,560||398|
In addition to the MBS's value as a feeding and resting area for migrating geese, the coastal portion of the sanctuary is important as a moulting area for Canada Geese. During spring migration, some ducks may remain in the sanctuary on the offshore islands and the mainland, and attempt to nest. However, severe flood tides restrict the possibility of significant waterfowl production in this area. Large numbers of ducks congregate along the coastal marshes of the MBS each summer to moult. Thousands of ducks utilize the tidal flats, coastal marsh, streams and ponds during the fall migration.
Many shorebirds, including Black-bellied, Golden and Semipalmated Plovers, as well as Yellowlegs, Dunlins, Semipalmated Sandpipers, Hudsonian Godwits, Red Knots and Wilson's Snipes, pass through Hannah Bay MBS during migration.
Access and Activities
MBSs are established for the protection and conservation of migratory birds. Activities that could harm migratory birds, their nests or their eggs are prohibited.
MBSs can be and have been established on private, provincial, territorial and federally owned lands. Access to each MBS varies by site and is at the discretion of the landowner and land manager.
Where MBSs are located on federal land, Environment and Climate Change Canada is responsible for the management and protection of migratory birds, nests, eggs and habitat. Where MBSs are located on provincial land, Environment and Climate Change Canada is responsible for the protection of migratory birds and their nests, while the chief game officer of the province is responsible for the management of habitat. Where MBSs are located on private or municipal land, Environment and Climate Change Canada is responsible for the protection of migratory birds and their nests. Habitat management is the responsibility of the landowner.
The standard prohibitions under the Migratory Bird Sanctuary Regulations apply to Hannah Bay MBS: hunting migratory birds is prohibited, and no person shall disturb, destroy or take the nest of a migratory bird or have in his or her possession a live migratory bird, or a carcass, skin, nest or egg of a migratory bird, except under the authority of a permit issued by Environment and Climate Change Canada or unless authorized by the Regulations. Possession of firearms or other hunting appliances is prohibited. Dogs and cats must not be allowed to run at large.
Access prohibitions or restrictions by the MBS landowners (the Province of Ontario manages the land and the Government of Nunavut manages below the high-tide mark) may also apply.
For more information on entry, activities and permits in MBSs, please visit the Management and Activities section of the Migratory Bird Sanctuaries website. For more information on Environment and Climate Change Canada's protected areas, please contact the regional office.
For greater certainty, nothing in this document shall be construed so as to abrogate or derogate from the protection provided for existing Aboriginal or treaty rights of the Aboriginal peoples of Canada by the recognition and affirmation of those rights in section 35 of the Constitution Act, 1982.
