2cy+ October. A rather typical fresh 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 very narrow. 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 (is often smaller than this, and may even be missing), quite diffuse, whitish and has a rather square shape with clear corners. [CS00451]
