A 4cy individual. The right-hand photo shows well the state of primary moult. New p5, with a solid black bar subterminally, is just emerging past p4 while p6 is still relatively short (part-grown) and falls in line with the tip of p3. The outer primaries are old and third-generation (note small whitish 'mirror' on p10) while the primary-coverts display extensive blackish sullying.
