Of course, calling all of these Cackling Goose is presumptuous due to the
clear variation in size in Canada and Cackling geese and the distance I was
observing at. My call was actually more based on the fact that the eagle
appeared significantly larger. Please disregard or discount that
declaration of specific *Branta *species.

Still a very cool observation!
