Iemand een idee welke oudersoorten dit op hun geweten kunnen hebben?

Have a nice day!

Snavel doet me aan Kleine Rietgans denken en in het kleed zijn sporen van Brandgans te zien. Ik zit dus te denken aan Brandgans x Kleine Rietgans.

Alcedo atthis

This is a hybrid between two Anser geese. One parent is Emperor gooser (Anser canagicus).

The scaly pattern on wings and mantle, the shape of the white head patch , and the partly dark undertail coverts are very typical for hybrids of Emperor with some other Anser species.
See here an Emperor goose x Greater Whitefront as an example:

and here an Emperor goose x Lesser Whitefront as another example:

However, what is the other goose involved?

Emperor goose has a fairly small bill, black and pink, and this bird has a good sized mainly black bill.

This makes me think of Swan goose (Anser cygnoides) as the second parent. The warm brown neck coloration would fit also, but the pattern of the neck is not like swan goose.

However,  it seems possible that the swan goose neck pattern may not be expressed  (or not always) in this type of hybrid.

On the other hand it could also be an Emperor -Bean goose hybrid, there the neck coloration should also fit- if it is that, perhaps Emperor x Taiga bean goose?



Any more photos showing that bird from other angles?

I have seen this bird also last year. I have notice this bird in the field as a Emperor -Bean goose hybrid. I have not taken pictures.
See also the patern on his bill.
