(last update: 22-2-2011)

LBBG 3cyAugust 22 2002, Papegaaienbek - Maasvlakte, the Netherlands.

3cy LBBG moulting the primaries: P6 is slightly longer than P5, P8-P10 are old second generation primaries. As can be seen in most second generation p10, from underneath the outer-web appears whitish. This bird is moulting most of the wing coverts, still there are central greater coverts growing in. Note the extensive dark centra of some of the central tertials.
