CURACA, Brazil — All Spix's macaws are majestically blue in the blazing sun of Brazil's Northeast, but each bird is distinct to Candice and Cromwell Purchase. As the parrots soar squawking past their home, the couple can readily identify bird No. 17 by its smooth feathers and can tell No. 16 from No. 22, which has two beads attached to its radio collar.
It showed that northern Bahia state, including Curaca, where the Spix's macaws are trying to survive, is now consistent with a desert area. It also identified the expansion of semi-arid climate in the Northeast, where nearly 55 million people live.'If the planet is warmer, there will be much greater evaporation. So, the water leaves the environment and generates aridity,' the director of Brazil's anti-desertification efforts, Alexandre Pires, told The Associated Press.
