The birds are ringed in the context of RAS in Nijmegen and Berg en Dal, The Netherlands. All birds have a combination three colour rings and a metal ring. On each leg two rings. The position of the metal ring is part needed to identify a bird. Beware: at other locations there may be other birds with the same combination of rings.
