Rewilding Argentina and the return of the Green winged Macaw

Since 2019, The Macaw Society has been a crucial supporter of Rewilding Argentina‘s macaw project through comprehensive training visits to our field sites plus virtual and in person advising. Rewilding Argentina’s team visited our field site in Tambopata in 2019 and 2020, where they learned to use methods for monitoring macaw chicks and studying nesting ecology. Indeed, the nest box the Rewilding Argentina team uses for the population of reintroduced Green winged macaws in Iberá was inspired by our wooden box model in Tambopata.

Throughout their partnership, both teams have closely shared experiences and knowledge. Insights gained from Tambopata’s wild macaws have been pivotal in establishing new populations of Green-winged Macaws in Iberá, Argentina. This collaborative effort highlights their shared dedication to macaw conservation, marking significant progress towards ensuring a thriving future for these majestic birds across South America.

In 2024, their collaboration extended to Bosque Escondido, Costa Rica, where they observed and contributed to methods for parrot reintroductions and post-release monitoring at the RESCATE wildlife rescue center.


Rewilding Argentina is an organization dedicated to the conservation and restoration of natural ecosystems in Argentina. They focus on reintroducing native species, protecting wildlife habitats, and promoting biodiversity. Their projects include the reintroduction of species like jaguars, giant anteaters, and red-and-green macaws in areas where they have been extinct or severely diminished.

Rewilding Argentina’s Macaw project focuses on the reintroduction of the Red-and-green macaw (Ara chloropterus) into the Iberá Wetlands, a region where this species had been extinct for over a century. The initiative aims to restore ecological balance by bringing back these vital seed dispersers, which play a crucial role in maintaining forest health. The project involves breeding macaws in captivity, preparing them for release, and monitoring their adaptation to the wild. This effort is part of a broader strategy to revive biodiversity and promote sustainable ecosystems in Argentina.
