An adult bird ringed left green ES98, ringed as pullus at the nest, June 26 1996, now 7cy. The primary tips are fresh. P9 shows a white mirror as well, although the head-shape indicates a female. Note the dark spot on the upper mandible. Note also the difference in age in the tertials, with a fresher, plain grey second tertial between the brown hued feathers. In this case, the code of the ring turned slightly yellow.

Nesting at the same location as the previous year, now in 8cy. ES98 has a clear yellow iris, without speckling, a red orbital ring, a red gonydeal spot confined on the lower mandible, no black on the bill by June 02, but still a whitish tip of the bill and it has a mirror on both P9 and P10. The complete moult hasn't started yet, with P1 still present.
