Dark goose


Attached are 2 photos of a rather dark Canada(?) Goose. The bird has been hanging around Esther Simplot Park for some time now, and it is very tolerant of humans, which is why I was able to get these photos with my phone. The bird is basically
shunned by all the Canada Geese in the park, even though it has the chin strap of a Canada. The front is not just dark but also somewhat streaked and the lower parts of the bird are much darker than a regular Canada.

Any thoughts?
