De roze poten en de geribbelde hals doen sterk aan grauwe gans denken, maar die kol....

The pink legs and the longitudinal ridges on the neck makes you think of a graylag goose, but then..... where does this white front comes from??

I think this is a hybrid Canada goose with a domestic goose which has chinese goose genes,
see a Canada x Chinese goose here, this is the other more canada-goose like phead and neck pattern they can show, not the more chinese -goose (or swan goose)- like pattern of head and neck as in the other thread.

Such hybrids can vary between the 2 extremes in neck patterns...

Another bird of such a hybrid combination, but with the frontal part of the neck somewhat lighter  (This can go even further so that you get such hybrids also with a very swan goose like neck pattern)

The hybrids here i would also consider to be the same combination, but juvenile birds.

However, if you seek the photos with Hybrid1, you see here the neck pattern is on the extreme towards the swan goose side.
