Spotted something wrong?

The Rarotonga starling is a greyish-brown bird endemic to a single South Pacific island, Rarotonga, in the Cook Islands. It survives in the native forest of the mountainous interior, above the settled areas of the coast. Its total population is around fifteen hundred birds and depends entirely on that forest remaining standing and free of rats.

Fun facts

  • The whole species lives on an island of 67 square kilometres, and in practice only in the mountainous interior: the lowland forest was replaced centuries ago by crops and settlements.
  • It is one of the few native birds to have survived on Rarotonga after the arrival of rats, cats and common mynas, a combination that finished off several of the island's species.
  • Its population is stable but tiny, so the species depends entirely on the control of introduced predators in the interior of the island.
