Inglenook Farm, Rainford by-pass, St Helens

1000 Pink-footed geese in fields near Inglenook Farm today. I stopped and had a good look through them but couldn't find any other species.

I'm not sure what to make of this goose. Pretty sure it's not a hybrid, because apart from the perfectly symetrical white band it was otherwise just another pink-foot. Probably partially leucistic I suppose, though why it should form such a perfect band is a mystery.
