Michael Keys and his son, Larkin, will hike deep into the open savanna of pine trees and brush, carrying ladders and chain saws. Keys will climb 30 feet up a pine tree and spend three hours carving a hole in the tree to insert a wooden box.
Within weeks, Yellow-headed Parrots will nest in Keys' artificial cavities and produce offspring scientists hope can boost the population of the endangered species.
It's not your typical vacation in Belize, a small Central American country on the Caribbean coast. But it can make a difference.
"This is a species that could go extinct and I have this one specialized skill that can help," Keys said. "I'm not a heart surgeon or anything. So this is my contribution to helping the habitat."
