We have been so lucky! me and Lukasz Borek were ringing chicks in one of the West Pomeranian gull colony. We chanced on death metal ringed Common Tern (Sterna hirundo) and first didn't belive >>> [INORM SAFRING UNIV. CAPE TOWN S.A. 4H511**]
More than months past since we send the email to the S.A. station and still haven't got any ringing data (for me best rocovery since i've started bird watching :) )
