Juvenile Black-headed Gull. The underside of the primaries is predominantly dark, with the exception of P9 and P10. The underwing coverts and secondaries are light gray.
The body in this individual has turned mostly white (with brown markings on the flanks only), thereby creating a dark breast band.
