Species info: Cackling Geese are found in North America; they breed in arctic and subarctic habitats. Females select grassy, elevated areas in the tundra to build their nests. Once thought to be a smaller subspecies of the Canada Goose, they are now considered their own species. Other than their size, they do look very similar to the Canada Goose. During the winter, or non-breeding season, they migrate south to parts of the United States and Mexico. They get their name from their distinctive, high pitched call.
