Photo 9: LBBG adult, August 18 2001, Missouriweg Maasvlakte, the Netherlands.
At least p5-p10 are old primaries. This is a metal ringed LBBG of unknown origin, breeding in the Maasvlakte colony. The inner greater coverts have been shed and most of the old scapulars and wing-coverts look very abraded, yet do not show a clear brown hue. This may be an indication of British origin.
