Regarding white chevrons in the primaries of juvenile Arctic Jaegers, Olsen & 
Larsson 1997 state on p.131, (character number 9 of 13) 'Primaries have narrow, 
but distinct pale tips, diagnostic when arranged as arrowhead marks (similar to 
pattern on adult gulls): a good character on settled birds, but visible also in 
flight at very close range'.
I agree though that in this bird those pale edges could be produced by 
bleaching not just wear.
