Knowledge of spatial distribution for the stopover habitats of migratory raptors is a prerequisite to understanding their stopover ecology and managing their habitats. East Belitung is the important stopover habitat of migratory raptors, Oriental Honey Buzzards (OHBs Pernisptilorhynchus) based on satellite-tracking data taken in 2006-2009. The primary aim of this study was to analyze stopover habitats distribution of OHBs and their characteristics in East Belitung.Distribution and characteristics of OHBs stopover habitats in East Belitung could be determined by using geographic information systems (GIS) and satellite-tracking data. Logistic regression analysis wasused for analysing several environmental variables (i.e. slope, elevation, and distance to the several nearest land cover) for characterizing the landscape characteristics of OHBs’ stopover habitats. Results showed that the distribution of stopover habitats covered 2,453.14 km2 (94.93%) of East Belitung area. Habitat selection at stopover sites was highly influenced by availability of food. Identification of these landscape characteristics provide baseline information for ecological-based development of East Belitung and managing stopover habitats. |
