Some news from central Poland. On the end of November Michał Radziszewski observed a finnish Great Black-backed Gull (Larus marinus) on Wloclawek dam. The bird had been ringed in Espoo on summer 2010 as adult.
The Wloclawek dam on Wisła river is one the bigest hydroelectric powerstation in Poland. There is also a gulls colony: Herring Gull (Larus argentatus) & Caspian Gull (Larus cachinnas) and their hybrids.
