Something is happening in the heart of Rio de Janeiro that for over two centuries had remained only in natural history books: the return of blue and yellow macaw parrots – also known as blue-and-yellow macaws and ararauna macaws – to the Atlantic Forest. In the Tijuca National Park, one of the largest urban parks in the world, some specimens of the species have been reintroduced thanks to a captive breeding project and gradual adaptation to wild life. These birds, once common in the area, had disappeared by the 19th century due to intensive deforestation and illegal hunting, leaving a deep ecological void that was invisible for generations.

The rebirth of the Tijuca urban forest
The project is led by the conservation organization Refauna, which has been working for years to bring the Atlantic Forest ecosystem back into balance. The Tijuca area, approximately 10,000 acres of tropical vegetation nestled in the city, is now a natural rewilding laboratory. Before the macaws, other species had already been reintroduced: small rodents such as agoutis, turtles, and primates such as howler monkeys, all fundamental elements for rebuilding the original ecological network. The return of the macaws is considered a symbolic and functional passage: not only a spectacular event, but an essential piece for the regeneration of biodiversity.
The delicate work of birds’ adaptation
Currently only a few specimens have been released into the wild, after a period of observation and “training” that lasted weeks. The birds, coming from captivity, must recover the ability to fly long distances and learn to recognize food, sounds and natural environments. The definitive release is expected at a later stage, when environmental conditions are more favorable and the animals have developed sufficient autonomy. This step-by-step approach is critical to increasing your chances of survival.
An ecosystem that breathes again
The value of the project goes beyond the stage presence of the Macaws. These colorful parrots play a key role as seed dispersers: their powerful beak allows them to open hard fruits, contributing to the spontaneous regeneration of the forest. The Atlantic Forest, in fact, has lost up to 90% of its original cover, and many plant species still depend on animals to reproduce. The return of the macaws could therefore trigger a positive ripple effect on the entire ecosystem.
A future still under construction
For the citizens of Rio, macaws are not just animals: they are a national symbol, present in art, logos and collective imagination. Seeing them fly again over Tijuca represents a form of reconciliation between city and nature. Further releases are expected in the coming years until around 50 reintroduced specimens are reached. If the project is successful, the macaws could expand beyond the park’s borders, contributing to the rebirth of the urban Atlantic Forest. Their return, after 200 years of absence, is an experiment in the future, in which a city tries to give space back to nature without giving up on itself.
