Site Description
This well-known site covers a large area around the town of Churchill, Manitoba, a port on Hudsons Bay. Most of this area is exceedingly flat; the only variation in elevation comes from the Precambrian rocky ridge that follows the shoreline. The number of habitats found here is particularly high: in the southern portion, black spruce forests dominate, and in the north a band of wet and dry tundra parallels the coast. Within both regions are found ponds, lakes marshes and muskeg. Tidal flats and marshes are another important habitat for birds. The Churchill River, on the western side of the site, runs northward into Hudson Bay to where the town is situated. The best known mammal of the region is the Polar Bear, since Churchill is the largest denning area in the world. Seals, Caribou, Timber Wolves and Beluga Whales are also here in the summer; the latter congregate in the Churchill River estuary in the thousands to feed and give birth.
Birds
The Churchill area is known across North America for breeding and migratory birds that can be seen between June and September. Churchill has 95 breeding bird species, with over 250 species recorded in total. Many of these species are tundra breeding shorebirds, or pond and marsh breeding waterfowl. The most numerous, and the most famous of these, is the Snow Goose. In 1997, about 66,000 mid-continent Snow Geese bred in the salt marshes of La Perouse Bay, east of the town; it was estimated that 30% more birds were present if non-breeding adults were included. In 2011, 100,000 Snow Geese were observed flying through the area during spring migration. Churchill also has large numbers of migrating waterbirds. The Black Scoter passed through in significant numbers in spring. Smaller numbers of White-winged and Surf Scoter also pass through, as do Harlequin Ducks. Another waterbird, the Red-throated Loon passes through the Churchill River in significant numbers, with 440 counted on a single day in 2010.

Of the many shorebirds seen at Churchill, the Ruddy Turnstone is the most significant since up to 2.4% of the North American population can be seen in spring migration; a maximum of 6,000 birds were recorded in June 1982. In July,1999, over 1,500 Whimbrel were observed at Cape Merry and in July 2001, 50 Buff-breasted Sandpiper, a globally near-threatened species, were observed at Gordon Point.

Perhaps the bird that most symbolizes Churchill to birders is the Ross Gull (nationally vulnerable). This primarily Eurasian bird breeds in only two locations in Canada. Between 1978 and 2008, an average of one pair nested at this site, although in some years numbers have been as high as 6 pairs. Between 2008 and 2016, no Ross’s Gull were seen in Churchill. A single bird was observed in spring 2016 but none in 2017. Churchill is known for its diversity of gulls, terns and jaegers, including being one of the most important areas in North America for breeding Little Gull. Sabine’s Gull can be observed migrating along the Churchill River in early June and Long-tailed Jaegar is seen in most years. Parasitic Jaegar breeds here and as many as 6,000 Arctic Tern have been counted on a single day during spring migration.

A few of the many land-based birds at Churchill are: the Peregrine Falcon (up to 10 migrant birds); Willow Ptarmigan (breeding, and over 700 migrating birds); and Snow Bunting (fall, 12,000+).

Note: species shown in bold indicate that the maximum number exceeds at least one of the IBA thresholds (sub-regional, regional or global). The site may still not qualify for that level of IBA if the maximum number reflects an exceptional or historical occurrence.
 
Conservation Issues
In 1996, the eastern part of the Churchill IBA was included in the Wapusk National Park. The park management board holds members from several local interests, and all three governmental levels. In addition to park protection, the traditional Ross Gull nesting location, Akudlik Marsh, is protected as a special conservation area.

The Lesser Snow Geese population has exploded over the last few decades; this has meant increased salinity levels and vegetation change. Now, over half of the intertidal salt marshes in the region are no longer productive. Numerous biologists are extremely concerned and have recommended a reduction in their population, primarily through increased hunting. Other conservation concerns at Churchill include, environmental stress from tourism, gravel extraction and weir construction on the river. The first two are of concern partly because almost any heavy use of the arctic tundra can cause scarring and permafrost melt.


The IBA Program is an international conservation initiative coordinated by BirdLife International. The Canadian co-partners for the IBA Program are Birds Canada and Nature Canada.
