Wikipedia says that the greylag goose is found in many parts of the world, Lyn, where domesticated geese have gone feral. They will even create hybrids by breeding, for example, with Canada geese.
They are also well known for a fixed action pattern nesting behavior. Once they see an egg out of the nest, they are hardwired to return it in exactly the same way each time. If you put a door knob in the location of a wayward egg they will even use the same routine to pull it into the nest.
