Ringed as pullus at Tampere, Finland on July 11 1998, now in 6cy. A typical adult fuscus by mid-July. Most striking are the small size, the slender bill, the red gonydeal spot which normally doesn't exceed on the upper mandible, the dark upper-parts which turn brown hued when older and worn, the lack of moult in the scapulars, wing-coverts and the primaries and the small white tips on the outer primaries, which wear away quickly. Note the red spot which extends on the upper mandible in this individual and the strong brown hue on the old upper tertials and compare to the very dark fresh central median coverts and lower tertials. P10 has a large mirror over both inner and outer-web, but nonetheless P9 is lacking a mirror. Note also the primary moult score: P1 is new, P2 is growing, while P3-P10 old. PMS 9.
