Excerpts Adapted from the Birds of Saskatchewan:

The proliferation of garbage dumps and their replacement by giant landfills adjacent to all Saskatchewan towns and cities helped to fuel the population explosion of both California and Ring-billed Gulls in the last century. The California Gull breeds in the interior west of North America from the Northwest Territories south to mid California and east to Manitoba. This species winters along the Pacific Coast from southern British Columbia to southern Mexico.

Great Blue Herons use wetlands of all types and sizes, and are often seen wading along creeks, rivers, and the shores of wetlands. They are attracted to waters below man-made structures where fish and other prey concentrate. At breeding colonies and when roosting they perch high in trees.

The California Gull is a common summer visitant and locally common summer resident in the western and east-central portions of the province, north to Suggi Lake, Reindeer Lake, and Lake Athabasca (2 colonies). There are fewer than 30 known colonies in the province. As early as 1905-1906, A. C. Bent (1907) found the California Gull common "on or about the larger lakes and about the garbage piles near the towns,? referring especially to Maple Creek.
