Observations in Panama of two captive-bred harpy eagles Harpia harpyja, indicated that after release, prey diversity collected and predation rates were broadly consistent with that of wild birds (Touchton et al. 2002). In 1998 in captive breeding facilities in USA, two harpy eagles were hatched and reared using puppets (to avoid imprinting on human carers, see ‘Use puppets to increase the survival or growth of hand-reared chicks’ for studies on this intervention), then placed in an enclosure with an adult female eagle. Near fledging (161-165 days old) they were transferred to an aviary at a release site in Panama, where they were habituated for 4-5 weeks prior to release. They were provided with supplementary food until they ceased to visit (11 months). Both birds were recaptured and relocated to a nearby safer site, the male re-released on 16 June and the female on 10 October, 1999. The eagles were monitored during June 1999 to August 2000. Both made captures of wild prey with apparent ease, despite lack of human training or parental guidance.
