One in front seems like dark morph but next one I'm not sure.
According to my guides white morph supposed to have black primaries and I don't see any on that bird.

Thanks

Snow Geese of both varieties have dark wingtips. These are domestic geese.

I thought that pink bill and legs differentiate them from domestic ?

Domestic geese cannot fly or if they do they usually fly badly... They're heavier and usually their weight distribution causes drag.. This bird is a good flier... so I'd say it's probably an albino/leucistic Snow Goose or a domestic/wild hybrid..

Not true.. Almost all are descended from Greylags.. (ex Chinese Geese) Even white breeds mostly have orange bills and feet...

Both are domestic goose x Canada Goose hybrids. With white domestic crosses such hybrids rarely show the dark feathers of their Canada parent and bill always pink.

Domestic Graylag x Canada hybrid for both would be my best guess,

Little difference between pink & orange from any distance; I was assuming you meant pink vs. black bills, which some domesticated breeds (derived from Chinese geese) do have. And the legs are pink, even when the bills are orange.

But worth adding that the eastern subspecies of Greylag (A. a. rubrirostris) has a genuinely pink bill, and is also involved in the origin of some domesticated goose breeds.

I agree Nutcracker... There's even a Polish race of Mute swan with pink feet...

Just a quibble...'Polish Swans' are not a race of Mute Swan but just a genetic form where the cygnets are white and the legs & feet are pinkish. They do not originate from Poland either but occur in all populations.
