Anser anser x ??? hybrid Netherlands

Hi,

photographed this geese in Netherlands on a field near Amsterdam inside recreation area from Het Twiske.

tree (2 where grey and white bird) hybrids seen in that flock.

in IMG_7314small.JPG and IMG_7350small.JPG is the same bird -- A.anser with ???.
in IMG_7309small.JPG -- A.anser with B.leucopsis? (this one was outside of that flock)
in IMG_7326small.JPG -- A.anser with with a domestic one?

another hybrid was in the company of two domestic geese.

sorry for the quality but the weather was miserable.

thanks for your answers,
cosmln

Hi Lou,

dont think so, the structure and coloration of the beak here is something occurring in barnacle x greylag, and the breast is blackish , that there is a white belly patch starting at the lower breast is also something not uncommon in this hybrid (also in Barnacle x greater whitefront that seems a common belly pattern).

here is another hybrid barnacle x greylag with a similar pattern to the one in the 3rd photo.

As you see, these can be quite close to canada x greylag sometimes (And some individual birds may be very difficult and not always easily identifiable)
