Recently Lukasz spent a weekend in Mrzezyno with his family. By the way he colour-ringed some Herring gulls (Larus argentatus) and Black-headed gulls (Larus ridibundus), but the most interesting bird was the Goosander. The moulted male rested at the harbor, where Lukasz caught him using fishing line.
We have more than 300 ringers in Poland but last year no one caught any Goosanders (see the polish annual ringing raports).
