“Habitat loss and the illegal pet trade drove the red-tailed amazon (Amazona brasiliensis), endemic to the southeastern Brazilian coast, to fewer than 5,000 individuals by the end of the 20th Century.

Thanks to a project to install artificial nests on an island on the Paraná coast, the number of parrots almost doubled in 20 years, taking the bird from ‘endangered’ to ‘near threatened’ status, the only case of its kind in Brazil.”
