Yellow-legged Gull michahellis 2CY, April 30 2003, Etaples, NW France (50.42N,1.34E).

2CY michahellis from late-April. This bird obviously started the complete moult (second pre-basic moult), as it shows a large gap in the median and lower lesser covert bars. Fresh feathers are still not visible -the complete moult just started- and the wing-covert panel shows a mix of abraded juvenile feathers (e.g. the central and outer greater coverts), broad barred old second generation feathers (e.g. the innermost greater coverts and inner median coverts) and missing feathers in the outer median and lower lesser covert bars. In the lower upper scapulars, fresh third generation scapulars have been moulted, which show a grey base.
