Release captive-bred individuals into the wild to restore or augment wild populations of raptors Bird Conservation

A study from wetlands in Kentucky and Tennessee, USA (Altman 1983), describes the successful release, through hacking, of a captive-bred, juvenile bald eagle Haliaeetus leucocephalus in summer 1981. The eagle was fed in an enclosure until 14.5 weeks old and began flying immediately after it was released. The eagle remained close to the release site for 39 days, hunted successfully (with a 50% success rate) and appeared to behave normally until it dispersed from the study area.
