Refauna started restoring the rainforest through its “refaunation” programme, introducing the red-rumped agouti – a long-legged rodent the size of a cat – in 2010, followed by other species that exist elsewhere in Brazil but were extinct in the park. These include the brown howler monkey, which was probably last recorded in Rio in Charles Darwin’s Beagle diaries in 1832, and the yellow-footed tortoise.

All the reintroductions have brought excitement and new visitors to the park but none are as beloved as the macaws. The large parrots, almost a metre in length, which can be found in other parts of Brazil and South America, are famously intelligent and mate with their partner for life. The blue-and-yellow macaw adorns artwork, T-shirts and tote bags across the city and beyond, its colours echoing the country’s national flag.
