摘要：
The mean home-range size of the Javan Hawk-Eagle (Spizaetus bartelsi) on Java was estimated to be ca. 400 ha based on three different methods. The distance between nests of neighboring pairs was ca. 3 km in Gede-Pangrango and 2 km in the Salak Mountains. In the Halinum Mountains, the mean distance between territories was 1.8 km. Radiotracking of one adult male indicated a home-range size of 300 ha in the nonbreeding season. This finding Suggested that earlier population estimates probably were too low, as they were based on home-range estimates of 2000-5000 ha per pair depending on habitat quality. The species should Still be considered endangered, as it is threatened both from habitat loss and illegal hunting.
