Composition of Bird Guilds Type in Modified Secondary Forest at Curup Tenang of Muara Enim Regency South Sumatera

The condition of habitat balance can be identified by the structure of bird guilds in an ecosystem. Curup Tenang tourism area has modified secondary forest that indicated by human activities. The study was conducted on 6-8 August 2019 with the location of the study in several locations of Curup Tenang tourist areas, namely in the parking lot and its surroundings, the biodiversity park of Bedegung and its surroundings, the waterfalls of Curup Tenang and surrounding areas. The study found eight types of bird guilds, namely insectivores, frugivores, carnivores, omnivores, granivores, piscivores, insectivores, frugivores and nectinivores. Most guild members found were insectivores with 43 species of members. The structure of food network pyramids that can be compiled from the results of the study are granivores and frugivores, and pure carnivores occupy the top rank with members of 3 species. The existence of pure carnivores is very important to control the guild population that is below it. Correspondence: Email: fajar.sitanggang@bi.itera.ac.id
