Sooner than exspected our nice Polish "Kaspar-Hauser"-swift Gwizdek learns to be a real swift again! And he is happy! Maybe because of the company of our other Polish guest Tutus...? The same language?
Anyway, they are close together now - Gwizdek, Tutus and the German swift Spartan! - and enjoy to preen each other and to look out of the window.
We are happy too - first step to a life as a normal swift!
