Status, Diversity, and Feeding Guilds of Avifauna in the Mining Area

Abstract

Abstract Birds contribute to the ecosystem by delivering a variety of ecological services. Birds help the ecology by performing a number of ecological functions. Specific habitats determine bird distribution and community structure. The variety and feeding guilds of birds in various land covers were studied at PT. Vale Indonesia’s mining concession. We studied birds’ variety, status, and feeding guilds in three distinct land covers using the point count methods: i) primary dryland forest; ii) secondary dryland forest; and iii) shrubs. Data were obtained from January 20 th to February 24 th , 2020. There were 38 species from 24 families reported. We discovered 11 Sulawesi endemic species, and 1 vulnerable species. Secondary dryland forest species composition was more similar to primary dryland forest than to shrubs. Carnivores, frugivores, granivores, insectivores, nectarivores, and piscivores make up the fowl. The insectivore bird composition was the highest, while the piscivore bird composition was the lowest. The availability of food supplies and vegetation characteristics may be critical to the diversity of birds in any ecosystem. As a result, this study indicates that land-cover alteration and modification may have an impact on bird diversity structure. Maintaining vegetation as a source of food and habitat for birds is crucial for bird conservation.
