This colour-ringed greylag goose was present just to the east of the reserve last week. If you look closely at the image you can just make out the white XX, the S is around the other side.
Research on the Internet has managed to track down the origins of the bird. The bird was originally rung by a group of Dutch ringers in June 2009 at a place called Reeuwijkse Plassen (look for it on Google maps) close to the Dutch coast. The bird stayed at this site until January this year and our sighting is the first one away from Holland. Interestingly, I have heard of several other green neck-collared birds in Norfolk recently so there has been a movement across the North Sea in recent weeks.
If you see any of these birds or any other colour-ringed species, please let us know.
