Both Trinidad and Tobago used to be a part of the South American mainland. Over the last 1.500 years, big predators like the harpy eagle and the jaguar have disappeared from Trinidad. Ocelots and tayras now top the food chain. Its other inhabitants have adjusted, like Trinidad’s capuchin monkeys, topping up their menu by cracking snail shells on mangrove branches. Nocturnal oilbirds nest in dark caves, using echolocation to get around.
