Birds play an important role in the ecosystem. However, the species composition of birds in oil palm areas and their roles in balancing the ecosystem are still minimally understood. Hence, this study was carried out to investigate them. A study on bird species composition using the point count method in oil palm areas was conducted at three oil palm estates located in Northern Sarawak, Malaysia. A total of 72 bird species belonging to 30 families including one vulnerable and six near-threatened species have been recorded from 123 points. Bird species richness was the highest in Sebungan and Sabaju Estates and the lowest in Taniku Estate. Twenty-six out of 72 species of birds were common to these three different oil palm estates. Seven species consisting of Oriental Magpie Robin, Long-tailed Parakeet, Yellow-vented Bulbul, Greater Coucal, White-breasted Waterhen, Spotted Dove, and Malaysian Pied Fantail were the dominant species recorded in all estates. Ardeidae, Cuculidae, Nectariidae and Cisticolidae were the most diverse bird families in oil palm areas. Knowledge of bird species composition in oil palm areas could provide a better understanding of their importance towards bioindicator species to the ecosystem and the conservation actions to be taken.

Abstract

Birds play an important role in the ecosystem. However, the species composition of birds in oil palm areas and their roles in balancing the ecosystem are still minimally understood. Hence, this study was carried out to investigate them. A study on bird species composition using the point count method in oil palm areas was conducted at three oil palm estates located in Northern Sarawak, Malaysia. A total of 72 bird species belonging to 30 families including one vulnerable and six near-threatened species have been recorded from 123 points. Bird species richness was the highest in Sebungan and Sabaju Estates and the lowest in Taniku Estate. Twenty-six out of 72 species of birds were common to these three different oil palm estates. Seven species consisting of Oriental Magpie Robin, Long-tailed Parakeet, Yellow-vented Bulbul, Greater Coucal, White-breasted Waterhen, Spotted Dove, and Malaysian Pied Fantail were the dominant species recorded in all estates. Ardeidae, Cuculidae, Nectariidae and Cisticolidae were the most diverse bird families in oil palm areas. Knowledge of bird species composition in oil palm areas could provide a better understanding of their importance towards bioindicator species to the ecosystem and the conservation actions to be taken.
