Vega Gull (vegae) 2nd cycle, December 27 2009 - January 04 2010, Choshi, Japan. Picture: Chris Gibbins.

See Chris's BLOG.

2nd gen flight feathers, except maybe for a small group of central secondaries which look more mature. These feathers may be 3rd gen, which would be in line with the few grey GC on top of them. Note mirror on P10.
