3cy+ March. A rather typical adult wing showing uniform, dense and rather broad GC. Note that the over all pattern is slightly less contrasting than in juvenile GC. The brown outer edge is less warm, slightly broader and more diffusely set-off to the dark centre. The centre is slightly paler and less contrastingly dark grey, and on the outer vane it barely reaches the feather tip since the 'channel' betwen the shaft and the pale spot is rather narrow, and there seem to be very fine brown fringes remaining in the feather tip. Note also the lack of a black 'hook' below the pale spot, caused by the broader brown outer edge. The pale spot is rather small (may even be missing), quite diffuse and whitish. In this bird the spots are less square shaped with rather weak tendency to show corners. [CN89676]
