36 Iguaca! Iguaca! a group of parrots squawked as scientists moved them
from Luquillo Aviary to a new aviary in Río Abajo (REE-oh-ah-BAH-hoh) Forest.
This forest is less humid than El Yunque, and many parrots had once lived there.
Now there were two safe places for captive parrots to live and raise chicks.

37 Río Abajo Aviary opened in 1993. It had some challenges. Thunderstorms
sometimes caused the incubators to lose power. The scientists found
generators that kept the power flowing to the incubators.

38 The scientists also tried some new ideas. They kept more aggressive pairs of
parrots away from gentler ones, so the gentler birds would not be frightened.
They also caged young parrots with adults, so the birds could see how adult
parrots behave. The number of parrots in the aviary grew. By 1999, Río Abajo
Aviary had fifty-four Puerto Rican parrots. The recovery program was ready for
the next part of its plan: releasing adult parrots raised in captivity into the wild.

aggressive If someone is aggressive, he or she is often angry and ready to attack.
