Slight contrast in shade of grey-brown on primaries, with outer-webs of outer primaries darker than the inners (which advocates kumlieni). On the single feather P5-P9, outer-webs are obvious darker than inner-webs when looking closer at the outer primaries. Sub-terminal chevrons most obvious on inner primaries. Pattern of tail-band broken by much vermiculation, where typical kumlieni shows a more solid band, especially on the centres of the feathers.
