Cocos Cuckoo

Coccyzus ferrugineus

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The Cocos cuckoo is endemic to a volcanic island of 24 square kilometres lying more than 500 kilometres off the coast of Costa Rica. It is reddish brown with a cinnamon belly and moves unobtrusively through the understorey hunting large insects. Unlike many cuckoos, it is not a brood parasite: it builds its own nest and raises its own chicks.

Fun facts

  • The whole species lives on an island of 24 square kilometres more than 500 kilometres from the coast: Cocos Island is one of the most isolated tropical oceanic islands in the Pacific and holds several species found nowhere else.
  • Unlike the Old World cuckoos, it is not a brood parasite: it builds its own nest and raises its own chicks, like most American cuckoos.
  • Cocos Island was part of the inspiration for Isla Nublar in Jurassic Park and has been the scene of dozens of expeditions in search of pirate treasure, all of them fruitless.
