I took these shots today of a Dunlin amongst of flock of around 200 at Hayle Estuary. I found this obvious bird with its' bright leg rings ( double orange rings on the right leg, green flag on the left), but on closer inspection, I could see a vertical aerial stuck to its' mantle plus a second aerial attached to the tail. Whatever your personal opinion is on this new method of migration study, this individual seems to be unperturbed by the encumberance. (If it is a female, good luck to the interested male...)
