 The big one is a Canada Goose, Branta canadensis.

The two smaller geese are Cackling Geese, Branta Hutchinsii.

Wow - learned something new today - didn't know there was a Cackling Geese - wonder if I've seen them before because I'm sure I would have thought they were just small Canada Geese.

shorter neck, smaller beak, it's a separate species, based on mitochondrial DNA.

Lovely! I've seen both before as well, but not for a couple of years. Funny that I live in Canada but don't see Canada geese often.

It almost looks like the smaller ones could be the offspring of the Canadian Goose.
