Churchill is situated along Manitoba’s 1,400 km (870 mi) coastline, on Hudson Bay at the meeting of three major biomes: marine, boreal forest and tundra, each supporting a variety of flora and fauna. Each year, 10,000–12,000 eco-tourists visit, about 400-500 of whom are birders.
Starting in the 1980s, the town developed a sizable tourism industry focused on the migration habits of the polar bear. Thousands of beluga whales, which move into the warmer waters of the Churchill River estuary during July and August to calf, are a major summer attraction. Churchill is also a destination for bird watchers from late May until August. Birders have recorded more than 270 species within a 25 mi (40 km) radius of Churchill. (From Wikipedia)
