Bird ringed on the island of Schiermonnikoog, the Netherlands by Otto Overdijk. Scapulars form a grey saddle, contrasting with most wing-coverts, which are brown, old second generation. Rectrices and primaries also still old second generation. Note the replaced upper tertials, inner graeter coverts and few median and lower lesser coverts. Within two weeks, the bird flew from Madrid to the Netherlands.
