A bird ringed left red E21, right white E. This bird still shows a completely juvenile plumage, but note the fresh second generation-like lower scapulars and one upper scapular. Considering the location of these feathers, we presume them to be juvenile, obviously grown in later than adjacent feathers. E21 was ringed in the Maasvlakte colony this summer, about a month ago.
