Old technology still comes up trumps

While the new technology is exiting and grabs the public imagination, let us not forget that colour ringing still plays a very important part in many cutting edge ringing studies.  Jerry Lewis and his team in south east Wales, and Tony Cross and team in the north west have been studying what were thought to be two separate populations of Hawfinch. Imagine the excitement when garden Birdwatch regular Trevor Bashford who regularly photographs colour ringed Hawfinches in his garden took this shot of a white ringed male bird. His usual’s are yellow, so after a couple of frantic phone calls by the team it transpired it is one of Jerry’s from the south east. This is the first know movement between the two populations.
