Impact of behavioral differences on white-lipped peccary reintroduction success in the Atlantic forest

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Some studies suggest that behavioral variation among animals destined for reintroduction programs could influence their post-release survival and overall success. Therefore, we aimed to test whether individual differences in white-lipped peccaries (Tayassu pecari - WLPs) exploratory dispersal behavior after reintroduction. Using a standard ethological approach, described the traits of 17 captive WLPs along three dimensions: aggressiveness, exploration, sociability. Then, using spatial temporal unpredictability food supply, subjected 90 days pre-release training. Following this, moved enclosure at release site remnant area Brazilian Atlantic Forest. In this enclosure, maintained provide locally available fruits roots soft technique. After 32 days, released tracked movements next 12 months. As expected, displayed across dimensions analyzed. While sex age did not affect trait scores, an increase body weight was associated with heightened aggressiveness. The least sociable were first ones explore disperse site. Our results showed indeed influences exploration reintroduced WLPs. chances successful reintroduction, it is necessary develop training strategies are tailored individuals.

Free Flight Training as a Tool for Psittacine Reintroductions

Birds, Journal Year: 2024, Volume and Issue: 5(3), P. 522 - 542

As habitat loss and other threats accelerate, ecological restoration reintroduction science are becoming progressively more important. The psittacines among the most endangered bird groups prime candidates for through reintroduction. Unfortunately, post-release survival of captive-raised animals is often quite low because, in part, high predation rates, site fidelity, poor flight ability, flock cohesion. Current best practices parrot release hold birds captivity a year or include distinct methods to address each these challenges. Here, we conduct small-scale, proof-of-concept study using free human-socialized trained adult hand raise group six fledgling Blue-and-yellow Macaws their historical range southeastern Brazil. All released showed strong cohesion fidelity site, avoided predation, survived without supplemental feeding over one year. One was captured by local people but recovered rereleased it has reintegrated into still alive doing well. modeled both desirable behaviors (flocking, foraging, reacting predators) undesirable they were returned before conclusion this study. Our suggests that training great potential help young attain broad array vital skills needed post-release.
