I was very lucky yesterday to visit a merlin nest, under licence, with Tony Cross, bird ringer extraordinaire. Five young were present, about 2 - 3 weeks old, and they were all ringed. As well as the BTO rings, they had colour rings fitted, and Tony would be very keen to hear from anyone who comes across them. The colour rings are pale lime green with black inscriptions. I was very impressed by the calm and professional way that Tony dealt with these stunning little creatures (see attached pic.)
