Yellow-legged Gull michahellis 1CY 262D November 2001, Westkapelle, the Netherlands. Photo by Pim Wolf. 

Note the third generation-like lower scapulars. This bird has all the wing-coverts and tertials still juvenile. Most of the scapulars have been replaced for second generation feathers, except a few rear lower scapulars, the ones covering the scapular coverts. The upper lower scapulars and upper scapulars are worn already, now these feathers were replaced up to four months ago. The second generation lower scapulars have no other pattern than a prominent black shaft streak on a grey-brown base; a pattern rather odd in 1CY michahellis.

This bird is ringed white 262D, from the south French colonies near Marseille, spring 2001.
