Overall, CJJR is a less advanced-looking bird than the previous individuals. Nonetheless, at the end of May (plates 1-3), the tail, most secondaries and P1-7 have been renewed; only the outer primaries (P8-10) and some inner secondaries in the right wing still are juvenile. P7 is still growing and P3 in the left wing seems to be missing. Throughout June, the three juvenile primaries are retained (plates 4-5) and towards the end of July, P10 is still present (plates 6-7). Only at the beginning of August, the last juvenile primary has disappeared; P7 then is fully grown (plate 8). CJJR was last seen at the end of August; at that date, P9-10 were not yet fully grown (plates 10-11).
