Finally found some time to ringreading. Today me and Lukasz were on the Miedwie lake. Saw nice flock of Common Cranes - about 520 birds. One had combinations of colour rings (probably become to german project).

Visited also Morzyczyn - gulls roosting area. Have seen there BHG with plastic ring and some with metal rings, all of them polish.
