- Аннотация: The species diversity, biotopic distribution, and interspecific relations of reed warblers were studied in 1998-2000 in Sosta lakes (Kalmykia). Acrocephalus agricola was found to be the most widespread and numerous species, which occupies a broad range of habitats, from dense reed stands to wet grass meadows overgrown with Tamarix shrubs. A. scirpaceus was found only in the most tall and dense reed stands, but not in narrow reed belts and Tamarix shrubs. A. arundinaceus inhabits edges of large reed stands adjacent to the open water. Small numbers of nonbreeding A. palustris and A. schoenobaenus are also in the composition of the warbler community. Breeding territories of all warbler species are overlapped freely. The species studied respond differently to severe droughts. A. arundinaceus leave lakes as soon as sand beaches separate reed stands from the open water. The number of A. scirpaceus is reduced drastically, while that of A. agricola remains unchanged at least during the first year of drought.
