LBBG adult MU6, Missouriweg, Maasvlakte, the Netherlands, March 30 2002. An adult bird ringed left leg orange MU6. When ring data become available, they will be added as soon as possible. Note the vestiges of winter plumage: the black markings on the upper mandible are still visible. Note also the large white mirror on p10, almost merging with the white tip at the outer web. |
