2cy (female) June. A very tricky bird showing two moult contrasts in GC, amounting to three generations of feathers. GC1-2 are retained juv, GC3-6 are post-juv and GC7-10 are recently replaced, 'pre-br' feathers. As no regular pre-br moult is known in this species (and the 'pre-br' contrast was not present in the other wing), this is for sure the result of an accident - note also freshly replaced TT8-9 and SS5-6. Remaining remiges juv and heavily worn, especially at exposed tips of outer PP. [DC40185]
