Darwin’s rhea, South America’s largest flightless bird, is being reintroduced to Patagonia’s Chacabuco Valley with 39 captive-bred chicks released in early 2026, marking a major step in reviving this endangered species through collaborative conservation efforts.

What happened
Between March and April 2026, Rewilding Chile successfully released 39 captive-bred Darwin’s rhea chicks into the Chacabuco Valley of Patagonia National Park. These birds were carefully bred at the Quimán Reserve, transported to the Aysén Region, and acclimated in pens before their release into their historical steppe grassland habitats. This marks a significant advancement for the decade-long rewilding project that began in 2014.
The program involves close coordination among multiple organizations, including Chile’s National Forestry Corporation, the Agricultural and Livestock Service, Carabineros de Chile, the Chilean Army, and international partners like Peru’s National Forestry and Wildlife Service. Community members from several nearby towns also participated, strengthening regional support and stewardship for the birds’ successful recovery.
Why it feels good
Darwin’s rhea, once widespread but decimated due to habitat loss and conflict with livestock, plays a vital role in its ecosystem by dispersing seeds that promote plant diversity and grassland regeneration. Restoring this species contributes to the health of the Patagonian steppe and supports other native wildlife, making this reintroduction more than a single-species success.
Community engagement in release events fosters a shared identity and collective stewardship for the region’s natural heritage, encouraging ongoing protection efforts. Tracking data from the released birds, especially one female that covered over 240,000 acres seasonally, provides valuable insights to guide future conservation strategies and habitat management.
What to enjoy or watch next
Future releases are already planned as breeding programs at Quimán Reserve continue to supply healthy chicks for rewilding. Monitoring the movements and behaviors of released rheas through GPS collars will remain key to understanding how best to support population growth and survival in the challenging Patagonian environment.
As Patagonia National Park restores native landscapes, observers can expect to see the expanding presence of Darwin’s rheas influencing grassland dynamics. This transformation promises ongoing ecological benefits and opportunities for local communities, tourists, and wildlife enthusiasts to witness a successful species comeback in one of Chile’s most iconic wild areas.
