Managed to properly read the rings on the Dark-bellied Brent Goose today, once the gloom had eventually lifted a little (red ‘F’ left leg, black ‘4’ right leg). The bird was ringed at Schiermonnikoog – an Island off the Dutch coast – on 10/05/12. It is carrying a GPS logger which can be downloaded using a radio antenna from a distance of a few hundred metres. This is the first of the GPS birds to have been recorded in Wales.
