Deze gans van Jolanda Wannet lijkt mij een hybride Grauwe x Kolgans. Let op de lichte staarttekening, de kleine donkere kop, de lange slanke vleeskleurige snavel. De zwarte nagel is mogelijk nog jeugdkleed.

From the pattern and the body shape and beak it could be Kolgans x Indische gans, but it looks Too dark for that- or is that just due to the photo???

With the combination of dark brown head and light grey wing coverts and tail pattern, you might even think that Pink-footed was involved. But the bill would be too long and too orangy for a Greater White-fronted x Pink-footed hybrid, I think.

Yes indeed, in my opinion the light grey back of the bird is something for Pink-Footed, but also for Bar-headed. The white face is pointing to Bar-headed as well.
I vote for Greater White Fronted Goose x Bar-headed Goose. The dark head is strange indeed.

Can Greenland Greater White-fronted x Pink-footed be excluded? Anything known about this hybrid in the wild?
