(CNN) The Spix's macaw achieved onscreen fame in 20th Century Fox's "Rio" as a charming parrot named Blu who travels thousands of miles in an attempt to save his species.

But a study released this week found that the Brazilian bird is now extinct in the wild.

The Spix's macaw is one of eight bird species, half of them in Brazil, confirmed extinct or suspected extinct in the report from BirdLife International . Deforestation is a leading cause of the Spix's macaw's disappearance from its natural habitat, according to the report.

Spix's macaw chicks are pictured in May 2014.

For the first time, extinctions on the mainland are outpacing those on islands, the study says.

"Ninety percent of bird extinctions in recent centuries have been of species on islands," said Stuart Butchart, BirdLife's chief scientist and the paper's lead author. "However, our results confirm that there is a growing wave of extinctions sweeping across the continents, driven mainly by habitat loss and degradation from unsustainable agriculture and logging."
