LBBG 1cy NLA 5.410.095November 01 2002 Westkapelle, the Netherlands.

Ringed in the Netherlands, Arnhem 5.410.095 on 24 June 2002 as pullus at Industrial complex Moerdijk, the Netherlands (51.41N 04.35E). The upper scapulars have been moulted to second generation and the lower scapulars still show many juvenile feathers in the lowest row. In the wing-coverts, some outer medians and #9 have been shed and #5-6 and #11 are growing second generation feathers. Note that the inner primaries in juvenile graellsii are not completely dark, but show a slightly paler inner-web (but confined to the inner-web, pale on the outer-web and apical spots are lacking).
