Brazilian police said Wednesday they were probing the outbreak of a lethal virus among some of the last Spix's macaws, one of the world's rarest birds -- made famous as the blue parrot in the 2011 animated film "Rio."

Until recent efforts to rewild the endangered species, the Spix's macaw had not been seen in its natural habitat for 25 years. Its conservation has sparked tensions between private breeders and the government.
