SOVON RESEARCH - Black bird

In the context of RAS at the Wylerberg, Beek-Ubbergen Black birds are being colour ringed.
Most are being caught using a mist nest in the context of CES.

Codes used:
Combination of three colour rings and a metal ring. On each leg two rings, while the metal ring counts in the code.
Observations of all colour ringed Black birds can be sent to me.
