(2 images) LBBG 1cy E63 E & E64E July 11-23 2004, Dintelhaven, the Netherlands.
E63 has the left wing completely juvenile, with 2 inner lc displaced or maybe missing. One rear lus seems missing.
E64 has all wing-coverts still juvenile in the right wing. One rear lus seems to be missing, but in the scores for 1cy LBBG research, it's only visible new feathers that are scored (to avoid counting damaged feathers, broken at the basal half. The remainder is not visible in such cases.
