A collaborative rewilding project has moved 15 Darwin’s rheas from Argentina to Chile to restore grassland ecosystems, preserve the species, and promote international cooperation in conservation efforts.
A rewilding initiative, involving Rewilding Argentina, Rewilding Chile, Tompkins Conservation, and local agricultural services, has successfully translocated 15 Darwin’s rheas (Rhea pennata) from Argentina to Chile. This historic project marks the first international effort to relocate a wild population of this species within South America’s Southern Cone. The birds were moved 55 miles (90 km) from Patagonia Park in Argentina to their new home at Patagonia National Park in Chile.
Known as ñandús in Chile and choiques in Argentina, Darwin’s rheas are native to the Patagonian Steppe. They reach heights of up to 1.1 meters and can weigh as much as 20 kg. These flightless birds play a crucial role in maintaining healthy grasslands by aiding in seed dispersal.
The need for this translocation stems from the overgrazing and hunting that have degraded the grassy habitats in the Aysén region of Chile, thereby threatening the rheas through destruction of nests. By relocating them, the hope is that these birds will help restore grassland health and ultimately support their own population recovery.
Throughout this project, researchers aim to observe the rheas and gather insights into their habits and spatial ecology. Tracking using GPS will also be performed to monitor their territory use. Such international rewilding efforts, though infrequent, are vital for preventing extinction and rehabilitating habitats.
As part of the rewilding protocol, the selected birds underwent thorough veterinary checks and quarantine both in Argentina and upon their arrival in Chile to prevent avian flu. They will stay in holding pens to acclimate to their new environment prior to release.
Kris Tompkins, President of Tompkins Conservation, emphasized the importance of international collaboration in conservation efforts, stating that reversing the mass extinction crisis requires such cooperative initiatives, particularly in view of nature’s lack of borders.
The translocation of Darwin’s rheas marks a significant step in international conservation efforts within South America. This initiative not only aims to restore vital grassland ecosystems but also facilitates research to broaden understanding of these birds. Furthermore, it underscores the necessity for cross-border collaboration in protecting endangered species and their habitats.
