E799 has the left wing completely juvenile, with gc 2 displaced.

E800 has some wing-coverts displaced in the right wing, but all scapulars and coverts still juvenile. 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.
