“…Reintroduction enables the reestablishment of populations of different parrot species bred for this purpose (Brightsmith et al, 2005;Earnhardt et al, 2014;Smales et al, 2000) or confiscated from illegal trafficking (Sanz & Grajal, 1998;Silva et al, 2021). Therefore, it is an important procedure to enable the destination of psittacines rescued from illegal wildlife trafficking.…”

“…Wildlife reintroductions are common conservation tools aimed at reestablishing populations of species within their historic geographic range (Armstrong & Seddon, 2008;Fischer & Lindenmeyer, 2000;Griffith et al, 1989;White Jr. et al, 2012). Reintroduction projects of Amazona aestiva help determine the destination of animals rescued from trafficking and provide more accurate information on procedures on this methodology, which can be applied to the conservation of other threatened species (de Azevedo et al, 2017;Silva et al, 2021;White Jr. et al, 2012).…”

“…At the end of the day, the nurseries were closed to prevent predators from entering at night. In the morning in the following days, the animals that had remained in the avian nursery were identified and the doors were opened again (de Oliveira et al, 2014;Silva et al, 2021). This procedure was repeated for one month (the period in which the enclosures remained in the area), and animals that did not leave during the period in which the doors remained open were always identified.…”

“…Monitoring was carried out at dawn and in the late afternoon (for 2 hours per period) to identify the animals around the release site (in trees) and the animals feeding in the feeders. When an animal was seen feeding on native fruits scattered in the study area, the plant species were also identified (Silva et al, 2021).…”

Introduction: Reintroduction is a procedure used to reestablish wild animal populations. Objective: The present study aimed to evaluate the success of reintroducing Amazona aestiva and investigate whether abiotic factors (temperature, humidily, and luminosity) interfere with the search for food supplementation in feeders installed in the release area. Methods: Pre-release evaluations were initiated with 59 Amazonas spp. Tests were run to stool parasitological tests, leukocytes, flight capacity, and level of animal-human interaction. In all, 33 animals were selected and sent to the release area, which is an ecotone between the Atlantic Forest and the Caatinga biomes. After release, visits to the feeders and survival in the area were monitored for a year. Abiotic factors were also recorded in these periods. Results: The stool parasitological tests revealed the presence of Heterakis spp. and Eimeira spp. The leukocyte parameters were within the reference values for the species. At least 50% of the released animals survived after one year, with recordings of reproductive events. Abiotic factors did not interfere with the animal visits to the feeder. However, the variable humidity best explained visits in the morning, while the variables temperature and luminosity most influenced visits in the afternoon. Conclusion: The reintroduction observed and presented here is on the threshold of the classification as successful. The installed feeders and artificial nests caused the animals to stay in the area for monitoring. Abiotic factors may influence daily behavioral decision-making related to the use of supplementary feeding in reintroduced parrots.
