The state of Rio de Janeiro is in the national and international route of the traffic of wild animals. The numbers of apprehensions in this state are raised and the CETAS-RJ receives a great number of animals per year. Projects of release and reintroduction of wild animals combined with scientific research must gain space so that destination of these animals to the natural environment can occur in an objective way. The objective of the study was to develop procedures for release, with individuals of Aratinga leucophthalma species, taking in consideration behavior characteristics, the social structure, the alimentary habits and to accomplish the monitoring of the animals during the release and the post-release, looking for results that come to aid in future projects. The work was accomplished at three different places: the CETAS-RJ, ocurred the handling before the release and the study of the feeding in captivity; the campus of the UFRRJ, where field work related with the feeding in free life was don; and in the RPPN S?o Benedito Farm in Rio Claro-RJ, where the release and the post-release monitoring ocurred. The work was accomplished between September 2008 and July 2010. The handling before the release was done by the preparation of a nursery to house 30 animals. The animals were grouped by flight capacity and domestication level. This stage was also composed by the accomplishment of clinical and labs exams, individual demarcation of the animals through rings and sexing exam. Of the selected animals there was prevalence of males. According to the clinical exams was not verified any aspect to make unfeasible the work. The study of the feeding in captivity was made through analysis of the supplied food and the amount of leftovers, verifying the preference through the alimentary behavior. Preference of the birds was revealed by the sunflower seed and the need of the maintenance and elaboration of new balanced diets appropriated to release programs. The field work tried to describe the alimentary items of species from the Psittacidae family. The importance of exotic vegetable species was revealed as food source for birds of the Psittacidae family in the campus. From the ten alimentary items observed only three were from native species. The release was accomplished by the model of soft release, after a period of acclimatization in the release area, which preceded the opening of the nursery. After the opening of the nursery a food support was maintained inside and outside of the nursery and the monitoring was accomplished collecting data in daily accomp. The birds went increasing gradually the distance traveled after the release and they were incorporating themselves to groups from the area. The soft release model used in this work guaranteed the success in the process of rehabilitation of these birds. The food supports maintained after the opening of the nursery were extremely important to guarantee the nutrition of the birds during the first days after the release, and to give them strength for recognition of the area and to look for new food sources.
