Not a particularly unusual movement, as we have previously had Siskin recoveries to/from Scotland, but the movement of Coal Tit Z050799 was completely unexpected - ringed as a juvenile on 29/08/15, it was killed by a cat on 27/06/16 at Burton-on-Trent, Staffordshire - 272 days, 146 km, 49 degrees. This record was checked by the BTO Recoveries Team as the movement was so unusual.
Ringing aims to understand what is happening to birds in the places they live and how this affects population increases and decreases. This knowledge is vital for conservation. It also gives information on the movements individual birds make and how long many live for. BTO.org
