Komposisi Guild dan Lebar Relung Burung Strata Bawah di Sipisang, Sumatera Barat

Abstract

Guild composition and niche breadth are important point on avian studies. This paper describes the guild composition and niche breadth of understorey bird in Sipisang, West Sumatra. The study was conducted since May 2002 until October 2004 for approximately 10 days each month (totally 284 days or 51.120 net.hours). Fifteen mist nets were operated on ground level separately on three locations, which made 60 m line each. Mist nets were operated from 6.00 AM until 18.00 PM, and checked every two hours. The captured birds were identified, ringed, measured, weighted, photographed and released. In total 1061 individuals were captured during the study; those birds belong to 103 Species and 28 families. Based on guild, study area was dominated by insectivore-frugivore birds (IF) both in species and individual level. Meanwhile terrestrial frugivorous (TF) became the lowest one. Insectivore-frugivore also recorded has the broadest niche breadth. The bird communities dominated by small birds, which have weight lower than 30 g.

Biology Learning Content Analysis on Aves Diversity: A Case Study at Kaduberureum Biodiversity Park’s PT Chandra Asri Petrochemical Tbk, Indonesia

“…There were 16 insectivorous species of Aves, i.e., Aegithina tiphia, Cacomantis merulinus, Cacomantis sepulcralis, Cacomantis sonneratii, Centropus bengalensis, Collocalia linchi, Surniculus lugubris, Dendrocopos moluccensis, Dinopium javanense, Dicrurus leucophaeus, Hydrornis guajanus, Lalage nigra, Malacocincla sepiaria, Orthotomus sepium, Pellorneum capistratum, and Pericrocotus cinnamomeus. Insectivore group dominance was a common condition in Aves communities, especially in forests (Novarino et al, 2008), and it was influenced by the presence of insect species in the area (Muhammad et al, 2018). As for insects, they are an easy-to-find type of Aves feed because insects are a group of animals that exist throughout the year, are diverse, and can be found in any layer of the forest (Abdussalam et al, 2021;Hardina et al, 2019;Supartono et al, 2015).…”

Bird diversity in several land use types in Boyolali, Central Java

“…Densely-covered land use types such as tree plantations and the secondary forest were also dominated by insectivorous guilds, as dense canopy cover can affect a high presence of insects [21]. The dominance of insectivorous groups is a common condition in bird communities, especially in forest areas [22]. The dominance of insectivorous bird groups was certainly influenced by the presence of insect species both in terms of population and species diversity, which shows that the two land use types are very suitable for insects.…”
