Why was Last Mountain Lake important in North American bird conservation?

Last Mountain Lake is historically significant to North American bird conservation because it was the site of the continent's first bird sanctuary, established in 1887.1

Located in south-central Saskatchewan, the lake serves as a vital stopping point on a major flyway for various species, including waterfowl, songbirds, hawks, and owls. It is particularly noted for its role in the migration of whooping cranes and sandhill cranes during the spring and fall. By providing a protected habitat, the sanctuary has played a foundational role in the ongoing efforts to preserve migratory bird populations in North America.21
