Abstract

Grey-backed myna (Acridotheres tricolor) is a critically endangered endemic bird of East Java with populations in nature fewer than 250 individuals. Baluran National Park is one of the last natural habitats of Grey-backed myna. This study aims to determine the relative abundance and habitat use of Grey-backed myna populations in several habitats in Baluran National Park. The relative abundance of bird populations was calculated using the encounter rates formula, while habitat use was analyzed using PCA. The study was conducted from October to November 2018 in savanna, forest-savanna, restoration-savanna, monsoon forest, acacia forest, and coastal forest. The results showed that the savanna habitat had the highest encounter rates of 11.16, while the beach forest habitat is the habitat with the lowest encounter rates of 0. PCA analysis shows the habitat use of Grey-backed myna tends to be determined based on the presence of Brachiaria reptans, Acacia nilotica, Corypha utan, dead tree trunks, and abundant trees with large diameter, also the few of Tamarindus indica and leaf litter. An understanding of the relative abundance and habitat use is important for the grey-backed myna conservation.
