Brazil’s Blue-and-Yellow Macaws Return to Rio After 200 Years

Rio de Janeiro is witnessing a remarkable ecological revival with the reintroduction of blue-and-yellow macaws to Tijuca National Park, marking their return after a nearly two-century absence. This ambitious “refaunation” project aims to restore the biodiversity of the urban park and reconnect residents with the natural heritage of their city.

A Lost Icon Returns

The last documented sighting of a blue-and-yellow macaw (Ara ararauna) in Rio de Janeiro was in 1818, recorded by Austrian naturalist Johann Natterer. TV BRICS reports that following this, the species disappeared from the region, likely due to deforestation and habitat loss. Images of these vibrant birds have long adorned Rio’s logos, clothing, and souvenirs, yet the actual presence of macaws became a distant memory for many.

The Refaunation Project

Biologists are spearheading the reintroduction effort through a captive breeding program. Focusing on Wildlife details that several conservation organizations are involved in returning animals previously poached from or displaced by deforestation in Tijuca National Park. These include howler monkeys, red-rumped agoutis, and yellow-footed tortoises. Four blue-and-yellow macaws were initially released in early 2026, with plans for further releases as conditions allow.

Challenges and Acclimatization

The reintroduced macaws, rescued from captivity, require a period of acclimatization before permanent release. explains that these birds initially lack the flight muscles needed to forage over long distances—approximately 6 miles per day—and need to adjust to the sights, sounds, and smells of their modern environment. The birds are temporarily recaptured and held in an aviary, with a potential permanent release planned for September when food sources are abundant.

A “Dream Come True” for Cariocas

Viviane Lasmar, director of Tijuca National Park, expressed the significance of the project, stating, “They are so magnificent. It’s no surprise that all the visitors are constantly asking how they can witness them.” She further emphasized the personal connection for residents of Rio, calling it “a dream come true” for cariocas (people from Rio).

Tijuca National Park: An Urban Oasis

Tijuca National Park, one of the world’s largest urban parks, provides a crucial habitat for this refaunation effort. My Modern Met highlights the park’s role in mitigating the noise of the city and preserving a remnant of the Atlantic Forest ecosystem.

Looking Ahead

The ultimate goal of the Refauna organization is to release fifty blue-and-yellow macaws into Tijuca National Park in stages, establishing a self-sustaining population. This project represents a significant step towards restoring the ecological integrity of Rio de Janeiro and reconnecting its residents with the natural world.
