Abstract
Javan Hawk-eagle (Spizaetus bartelsi Stresemann 1924) is an endemic raptor which can be found in Java Island, Indonesia. Its population number is continuously decreasing, then we need to conserve this species to keep and increase the number of population in their habitat. The purpose of this research was to know the daily behavior characteristics and to determine behavior development level of Javan Hawk-eagle before being released. This study was conducted from February 2014 and February to March 2015 in Raptor Sanctuary Field Project, Salak Resort, Halimun Salak Mount National Park, Bogor. Method was done by scan sampling and quantitative-descriptive analysis. The data collection was conducted by observing all of the eagle activities in the cage form the behavior characteristics observing were perching behavior, flying, whistling, hunting and ingestion. The time for the observation step was 30 days, 60 days for socializan stage and 7 days habituation stage. During the rehabilitation process, the Javan Hawk-eagle passed through various treatment before being wildly released to nature. The precentage of perching was (41%), flying (6%), whistling (24%), hunting (12%) and ingestion (17%). On the socialization step perching (48%), flying (1%), whistling (48%), hunting (1%) and ingestion (3%) then on habituation step perching (79%), flying (3%), whistling (0%), hunting (3%) and ingestion (14%). The treatment on observation, socialization, and habituation step had increased the hawk abilities, such as flying ability, watching ability and the way in prey catching. The change of behavior development and smilar behavior to the wild can be used as consideration before releasing the Javan Hawk-eagle to its natural habitat
