Looks like a hybrid with barnacle goose
Looks like a hybrid to me too, but how can you motivate that in this case...?
- sharply demarcated breastband?
- small bill?
- darkish bill? But how to exclude juv. blue snow goose?

It's indeed hard to motivate. It seems that the bird shows some spots on the head and the hindneck. Here is another question; is it possible for a juvenile Snowgoose to migrate to the Netherlands on its own?

Combinatie grootte, donkere snavel en ontbreken van verlengde grote dekveren sluiten zuivere Sneeuwgans uit.
