Description du site
Luck Lake, when it contained water, was always an important staging area during fall migration. Since the wetland enhancement, however, it has developed into a globally significant site for many water bird species. During the early 1990s, one-day fall peak counts for at least six bird species were of global significance (i.e., greater than 1% of their biogeographical population or greater than 20,000 birds). These species were: Tundra Swan - about 5% of the North American population; Greater White-fronted Goose - about 2.5% of the mid-continent population; Snow Goose; Sandhill Crane 1.6% of the global population; Hudsonian Godwit - about 6% of the population; and Franklin's Gull - as much as 3% of the global population. These percentages are all based on one-day peak counts. For many species, the actual number of birds using the site would likely be much higher if “turnover rates” were considered (i.e., the movement of birds through the site over the course of migration). During fall migration, Luck Lake likely supports the largest concentration of Hudsonian Godwits in Saskatchewan. In summer, nationally significant numbers of Marbled Godwits are reported, such as 1,500 in 1995, which is 15% of the Canadian population. In addition to these species, thousands of other shorebirds and waterfowl make use of Luck Lake during fall migration. Between September 1 and October 10, it has been estimated that the total waterbird population ranges between 60,000 and 100,000. The globally endangered Whooping Crane is also occasionally reported here during fall migration.
