I headed out today to look for Oystercatcher territories. Whilst I was on Oiseval the great skuas were paying me remarkably little attention so I decided to record some of their colour ring combinations.
Because the skuas nest in such close proximity on Oiseval it becomes quite a chore to walk this hill as the weeks progress. Luckily only one of a dozen or so pairs of birds swooped at me which suggests that breeding season isn't in full swing yet.
Turns out that all the colour ringed birds were ringed by Will Miles while he was conducting his PhD on skuas and petrels just a few years ago.
