Herring Gull NLA 5.420.564 2cy (argenteus), January 08 2009, IJmuiden, The Netherlands. In the left wing, all coverts and tertials are juvenile. The scapular-covert looks fresh, but is normally acquired rather late. Scapulars 75-99% 2nd generation. This bird was ringed on July 30 2008 after taking in release for more than 24 hours. On that occasion, ringed as L. fuscus, but clearly L. argentatus.
