Lee Barber works for the BTO, coordinating structured ringing schemes including the Constant Effort Site Scheme (CES), Retrapping Adults for Survival (RAS) and the Winter Ringing Project. These schemes produce a wealth of information on how our British and Irish birds are fairing on an annual basis (see the BTO’s BirdFacts pages). Ringing is licensed and volunteers can train under the supervision of a ringing trainer, like Lee, to become a ringers themselves. The information generated from ringing is fascinating and shines a light on our best known species.
