This particular goose is usually reported as a Domestic goose sp. x Canada Goose. It wasn't until recently when I met a more experienced birder, who in turn consulted other more experienced people, decided to list this hybrid goose as a Swan Goose x Canada Goose (hybrid). As a result, I also now list it as such when I report my bird sightings on eBird.

This goose is a semi resident to the area who disappears for a time and then returns. He has quite the personally - look at the slight head tilt in the photo - and will let you know (by a hiss) that you are to close to him.

In the geese hierarchy, he is the boss bird and also noticeably bigger the the other geese.
