In my opinion, for what that is worth, the 2 Red-necked Stints at the
FSTW on Sunday were adults moulting into basic plumage. Lindell's image
shows rusty-coloured feathers on the upper breast that are most
probably the last vestiges of breeding plumage rather than the first
stages of its development. The rusty feather margins of the mantle and
the lack of faint white lines at its edge along with the well-developed
post-ocular supercillium also suggest post-breeding adult plumage rather
than juvenal. Its companion was more advanced in its post-breeding
moult and hence paler.
