2 Greylags - 1 albino, 1 hybrid

After some internet trawling, I'd say that this is a Greylag goose x Canada goose hybrid. There's a full account of these at birdhybrids.blogspot.com dated 23 Feb 2014. Features that point to this id are:- dark neck, white face and throat, grey cap, white eyering, and black nail on bill.
