| Adult Lesser Black-backed Gull / Larus fuscus, Westkapelle - sea dike (The Netherlands) on 06 October 2009 |  |  |  |
Ringcode: 8105583, ringed as +4cy on 25 May 2004 in Halso, Bankera GoteBorg (Sweden)
Female intermedius from Sweden, unfortunately not ringed as pullus but catched as adult breeding on nest. The primary moult score is relatively low for early October, compared to western graellsii: P4 is full-grown, P7-P10 are still old with a small mirror on P10 (although the white tips are worn). The upper-tertials and randomly some coverts and most scapulars moulted as well, standing out against the brown and worn old feathers. Note the red gonys on the upper-mandible.
