Аннотация: The genus Acrocephalus is an extraordinary diverse group of birds which has been the object of many studies. However, there are still many unanswered questions left and several species remain almost unstudied. Blunt-winged Warblers are particularly poorly studied and there is a lack of data about its range, habitat, behaviour and breeding biology. In May 2012 we studied the population that breeds in Hunan Hupingshan National Nature Reserve, Central China. The first recording of this species in Hupingshan was made in 2010 but the management of the reserve has never included provisions for Blunt-winged Warblers and no research on this population has been done until the present study. The population size of Blunt-winged Warblers was small; the largest in one meadow was three pairs. Such low densities may be because some birds are still on migration at the end of May. All the birds we found were singing in dry thickets of Reeds (Phragmites spp.) or Wormwood (Artemesia spp.) which were >1.5 m high (elevation around 1500 m above sea level). The males advertised their territories,.by singing from near the top of a stem, sometimes flying into adjacent territories. Females arrived soon after the males and began to build nests straightaway. The song is very similar to that of Paddyfield Warblers Acrocephalus agricola, but male Blunt-winged Warblers did not react to playback of this song, they only reacted to song playback of their own species by singing and moving close to the speaker.
