Sumario:[EN] This study aimed to evaluate the postrelease survival and spatial distribution of farmbred red-legged partridges (Alectoris rufa) that were subject to a prerelease training program based on exemplary behavior and alarm calls given by adults that acted as experienced demonstrators in simulated predator encounters (wooden raptor models and humans). Two groups of partridges were released in this study: trained (intensively reared birds accompanied by tutors) and control (chicks reared without tutors). Releases were conducted in the fall and winter-spring during 2 consecutive years using a total of 44 trained and 40 control radio-tagged partridges. Trained partridges showed statistically higher mean values of survival (72.7 d), home range (13.04 ha), and dispersion (549.58 m) compared with nontrained partridges, with most nontrained birds failing to survive more than 2 wk after release. Trained adult partridges showed the best survival results (105.2 d). Taking all birds into account, causes of death were attributed to terrestrial predators (45%), raptors (18.7%), hunting (11.3%), and unknown causes (25%). Although values of variables reported here were lower than those reported in wild counterparts, survival time and spatial behavior of trained birds were close to that of previous data of parent-reared partridges and higher than that of farm-bred birds. This study aimed to confirm the potential of prerelease training techniques in present-day rearing systems. Farm-bred game birds, which normally suffer from high predation rates after release, could highly benefit from the use of cost-effective training techniques based on learning from experienced adults
