The role of the Warbles of the genus Acrocephalus Naum. as determinants of heterotrophic and consorts of autotrophic and heterotrophic consortia is considered. It is determined that representatives from more than 20 higher taxons of plants and animals (Aves, Mammalia, Gastropoda, Insecta, Araneae, Acari, Trematoda, Cestoda, Nematoda, Phragmites and others) have trophic, topical, fabric and transportation service links with Warblers, as a consortia determinants. At the same time, Warblers of the genus Acrocephalus are part of the autotrophic consortia of plants with tall strong stems (mostly Phragmites communis, Urtica dioica and others) and willows (Salix), sedges (Carex), true grasses (Poaceae), mosses (Bryophyta) and algae (Algae) and have topical and fabric links with them. The Warblers also belong to the first-concentre of many heterotrophic consortia of birds, mammals, amphibians, reptiles and invertebrates. The conclusion is that the destruction of the core of autotrophic consortia leads to the disappearance of heterotrophic consortia of Warblers. The complex network of consortial links in biocenosis is presented.
