Finally I (Becca) have managed to get rid of my ringing 'bogey' bird - the JAY! A fine example was caught whilst coming to a peanut feeder at our Cambridgeshire ringing site. These birds are hardy, strong and very aggressive! There is power in that bill! Jays take a 'D' ring, the same as Lapwing, Green Woodpecker, male Sparrowhawk and Redshank to name but a few. This bird was an adult (4) based on the black bars on the blue feathers on the primary coverts being aligned with each other (see below).
