In conjunction with BTO Wales, I have started a colour-ringing project on Blackbirds in the grounds of the University and anywhere between. This is to monitor the longevity of the birds, to see if breeding birds are resident or summer migrants, as well an being able to territory map the singing males. We fit an orange darvic ring on the left leg with 2 black digits e.g. AA, A3. This morning we headed out at 04.45 as males were already feeding and attempted to catch a few. Around Bangor, we saw many, but we only managed to catch 3. I say 'only', but I was really pleased with the catch and it's going to be very exciting to wander around the university campus and see colour-ringed Blackbirds!
