Bean Goose and Pink-footed can be ruled out by the lack of darkness near the base of the bill in a juvenile bird which this is and the bird is too big and has no eye ring so Lesser White-front can be dismissed. This leaves juvenile White-fronted Goose but which race. The most likely in terms of distribution would be albifrons but the colour of the bill is not clear in my opinion.
All pictures are the same bird, the angle of the sun could affect the colours.
