‘They’re a lot like us’: saving the tiny punk monkeys facing extinction

In the tropical dry forests of northern Colombia, a small team is gradually restoring the degraded habitat of the rare cotton-top tamarin

Luis Enrique Centena spent decades silencing the forest. Now, he listens. Making a whistle, the former logger points up to a flash of white and reddish fur in the canopy. Inquisitive eyes peer back - a cotton-top tamarin, one of the world's rarest primates.

I used to cut trees and never took the titis into account," says Centena, calling the cotton-tops by their local name. I ignored them. I didn't know that they were in danger of extinction, I only knew I had to feed my family. But now we have become friends."
