📷 - This bird certainly has all three species in it. If I understand correctly, it is likely ((Snow x Bar-headed Goose) x Swan Goose) x (Snow x Bar-headed Goose). In other words: 37.5% Snow Goose, 37.5% Bar-headed Goose, and 25% Swan Goose.

📷 📷 📷 📷 - From my understanding these birds are the result of a pure Graylag Goose breeding with a tri-species hybrid. Something like Graylag x (Swan x (Bar-headed x Snow)) Goose. See their likely parents.

Graylag x Swan Goose x Black Swan (Anser anser x cygnoides x Cygnus atratus)
Graylag x Swan Goose x Black Swan (Anser anser x cygnoides x Cygnus atratus)
At least two individuals in a park in Spain. Only Black Swans and Mute Swans present, and at least one Graylag x Swan Goose that one of the hybrids was seen with. I'm not able to find photos of any other geese from this location, and the bill looks larger and more swollen at the base than would be expected on Black Swan. It seems like the most likely option here is that all three species were involved.
