The Canada Goose was split into two species in 2004; the Canada goose and the Cackling Goose. These also have subspecies. Basically they look the same except the Cackling is smaller in size and has a shorter bill. They can usually be found or noticed by staying and traveling in their own flock, but as I found this is difficult. The Cackling breeds farther north and westward than does the Canada. The Cackling is seen more in the western United States.
