These are the Greenland race of White-fronted Geese (Anser albifrons flavirostris).

Thanks to Joern Lehmhus in Germany for identification and for pointing out the one centre and top left (same bird) has an unusual distribution of white on its face.

Darker than the Greylag goose and with white marking above beak and dark bars on belly.

Occasional winter visitor to UK. If from Greenland, orange beak; if from Siberia, pink beak.

(Lesser white-fronted goose does not visit UK - captive only - and is smaller, with pink beak and yellow eyering.)
