OK, I know no one but me is interested in these damn geese, but bear with me. The photo below is the goose family I've been observing over the past few weeks. At first they had six goslings and then four. The next time I saw them they still had four, but one was clearly adopted because it was much younger than the other three. I think this smaller gosling may be a little Canada Goose because it's got black legs.
I did catch a brief glimpse of some Canada Geese with their young in an isolated part of the river. They were partially hidden by trees and brush. When they saw me they began honking and ran for cover, which is the diametrically opposite of the behavior of the geese down river who expect people to feed them.
