Ringed in the Netherlands, Arnhem 5.410.095 on 24 June 2002 as pullus at Industrial complex Moerdijk, the Netherlands (51.41N 04.35E).

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). |
