The release of a rehabilitated raptor, defined as an effort to release the raptor back into nature, have been done in Indonesia; however, only about 2% were monitored for more than one year. This is because long time intensive monitoring using simple observation equipment is difficult to do because of limited resources. Thus, more modern equipment – oneof which is satellite radio used in this research – needs to be used. The use of satellite radio to monitor the movement of rehabilitated raptors was carried out for the first time in 2018 for juvenile male Javan hawk-eagles (N.bartelsi) and adult female Changeable hawk-eagles (N.cirrhatus). The results of the monitoring of these two types of raptors showed that they mostly used forested areas close to water sources. Both types of eagles had the farthest flight distance with an average distance of ± 1,000 m / day occurring at week 4. Thus, it can be concluded that the rehabilitation efforts for these eagles were successful and that they had adapted to their new habitats as wild raptors.
