Yellow-legged Gull michahellis 1CY, September 20 2002, Boulogne-sur-Mer, NW France.
Another example of a 1CY Yellow-legged Gulls with all the tertials still juvenile. In the wing-coverts several feathers have been moulted: the second greater covert, the second median covert, the third lower lesser covert and about ten lesser coverts. A few central lesser and lower lesser coverts are missing. Almost all scapulars are second generation now, except a few feathers in the lowest row of lower scapulars. Moult is obvious in progress in the under-parts: second generation feathers are growing in the hind-neck, sides of the breast and on the head.
