One of the larger waterfowl that we commonly see in the northern parts of North America is the Canada goose. Although they are quite common today the Canada goose was facing a serious population decline in the early to mid 1900s. this was due mainly to habitat loss and over hunting. A subspecies of Canada goose, the giant Canada goose, was thought to be extinct until a flock of them were found in Rochester, MN in 1962. To prevent these birds from becoming extinct hunting laws were changed and land was set aside to provide habitat. Since then there population has rebound and are now often viewed on by some people as a pest.
