Many indices of bird moult are not only species- but also population-related characteristics. Investigation of post-juvenile moult of black-faced buntings revealed substantial differences in its completeness for young birds in the south of Primorsky Territory in comparison with the birds from more northern populations (Khingan-Bureya upland). In Primorye, partial replacement of primaries was observed in the young birds of the first broods. Measurements of feathers before and after moulting revealed the difference in the length of juvenile primaries and analogous feathers of the next generation. On the basis of this difference, a procedure was developed that allows us to differentiate the major part of black-faced buntings in Primorye during autumn.
