Photo 15: LBBG adult, September 30 2001, Dannes (near Le Portel), France.

Adult LBBG with p5 new and p8-p10 still old. The central greater coverts have been shed and expose the secondaries underneath. Note that the white secondary tips are almost entirely worn away and the grey centres are brown hued at the top. The lowest tertials are missing, while #4 is growing and halfway it's final length.
