The above three images are of the much larger [and more aggressive] Canada Goose.
According to articles I have read on the Cackling Goose, their range is only as far north as Oregon. While looking for more material on the goose, I found this excellent article on "Distinguishing Cackling and Canada Goose" from "Sibley Guides".
What do you think? Are the geese in question really Cackling?
