摘要

The present study reports the discovery of the hitherto unknown breeding grounds of the large-billed reed warbler Acrocephalus orinus in the Badakhshan region of Tajikistan. A total of eight adult individuals were caught at three riverine woodland sites and breeding was confirmed at one locality. The identity of the birds was confirmed on the basis of partial sequences of the cytochrome b gene. Even among individuals sampled at the same locality, genetic diversity was surprisingly high. This was interpreted as the result of secondary contact between previously isolated or fragmented populations. The breeding range of the large-billed reed warbler is likely small and the species' habitat is under intense pressure from the collection of firewood and fodder. Consequently, the large-billed reed warbler remains of considerable conservation concern.
