A female Spix's macaw released from captivity at the site in 1995 was killed by collision with a power line after seven weeks. The last wild male disappeared from the site in October 2000; his disappearance was thought to have marked the extinction of this species in the wild. [19] However, wild Spix's macaws may have been sighted in 2016. [4]

Last year, two Spix’s macaw chicks were born in freedom — the first ones in decades— but they didn't survive. All released birds were equipped with radio collars designed to resist macaws ...
Spix described and named many birds, primates, bats, and reptiles. Altogether he described some 500 to 600 species and subspecies. Furthermore, several species are named after him. Among Spix's most renowned discoveries is the species Spix's macaw, named after the explorer by the German naturalist Georg Marcgrave. He died on 13 May 1826 in ...

One example was the natural hybridization of a Spix's and Illiger's macaw recorded in Conservation Genetics (2001), which demonstrated two species of macaws producing offspring ...
