Survival and adaptation in the wild of the farm game birds are the most important indicators for the game breeding success. Spring release of hand-reared Common pheasants (Phasianuscolchicus L., 1758) and Chukar partridges (Alectorischukar Gray, 1830) is a powerful tool to increase the breeding potential and the growth rate of population. However, the process is complicated and depends to a large extent on the preservation and development of birds’ wild instincts, proper breeding and dispersal, habitat selection and the period of releasing.Survival of 20 Common pheasants and 49 Chukar partridges, spring released in natural habitats in Bulgaria, was estimated using radio-telemetry. Pheasants were released in March 2011 and Chukars – in February to May 2010.During the first eight weeks after release 80% of Pheasants and 83.67% of Chukars died. Chukars survival rates did not depend on the method of releasing. Pheasants and Chukars survival rates did not differ, but Pheasants dispersion was lower. The highest mortality rates occurred in the first 2 weeks after releasing.
