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.
