The right-hand photo shows 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 and pc are old. In left-hand image, with wings folded, the overall appearance is quite adult-like apart from the uniformly dark primary tips (second-generation).
