I think this here could also well be Brand x Kol

I think many hybrids with Brandgans involved show a typical upperpart pattern. Greyish with black stripes. Ofcourse it is possible, if what you mention is right, that this upperparts are the Kolgans part, but I don't think so. In my opinion it is more likely Canadese Gans is one of the parents, along with a knobbelgans?

why not A. indicus as one of the parents?

Citaat
why not A. indicus as one of the parents?
then this would be the A. indicus hybrid with the least white on the neck i have ever seen...but I see it also has some single white feathers on the neck

Honestly , without more photos I cannot safely identify this...

from what I see in this single photo,  it looks most similar to Kol x Brandgans to me.... but this impression may change with more photos from different angles.
