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

Abstract

The balance of the ecosystem in a location is certainly related to the food-eating process that occurs in it. This long process is naturally used by natural organisms to flow the energy cycle chains that exist in each individual. The condition of habitat balance can be identified by the structure of bird guilds in an ecosystem. Quiet curly tourism area has a unified landscape landscape in the form of modified secondary forest. This is indicated by the presence of canopy cover that is no longer dense and modified by human activities. The location of the study this time was carried out in several locations of quiet curup tourist areas, namely in the parking lot and its surroundings, the biodiversity park of Bedegung and its surroundings, the curup waterfalls of calm and surrounding areas. The study was conducted on 6-8 August 2019. Field findings 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. Pure carnivore is a top predator in this quiet, steep landscape. Its existence is very important to control the guild population that is below it. So that the balance of the ecosystem in this location can be seen from the benchmarks of the existence of this pure carnivore type.
