When Canada Geese are first born, they look like young ducklings, with grey and yellow feathers - they do not at all look like they would grow up to have such distinctive black and white markings covering their head and neck.
There is clear definition between the white and the black feathers - it's as if there has been a line drawn down the side of the head so that the white doesn't fade into the black in any way. All adult Canada Geese look the same - with a white band that goes under their chin, but not over their head and then they have a pure black face and a long black neck that eventually hits their brown feathers that covers their body. The Barnacle Goose looks very similar to this, but it has a black body of feathers; not a brown one.
This goose is native wildlife species to North America, so it is not just from Canada. ... continue below the picture...
... It does however breed mostly in Canada and the northern United States. In some areas they are considered pests as there are just too many of them and they like to congregate in public parks where there is often a lot of people. This is mostly because they get fed by people, but also because it is an open space for them to all gather together in.
