Thanks to a successful 35-year captive breeding program in Cocos Island, the Guam Rail, or more popularly known as the Ko’ko bird, is no longer extinct in the wild.
Conservation efforts have led to the recovery of the Ko’ko bird, according to an update from the IUCN Red List of Threatened Species.
The IUCN says the flightless Koko bird is only the second avian species in history to recover after being declared extinct in the wild.
But despite these gains, IUCN said the bird is still classified as critically endangered.
The Ko’ko was once thriving on Guam but the intrusion of the brown tree snake into the island’s ecology caused its numbers to decline.
To address this, conservation efforts were implemented to increase its numbers.
Aside from the Ko’ko Bird, the latest IUCN update reveals genuine improvements in the status of seven other bird species and two freshwater fishes.
Captive breeding, combined with careful management of wild populations, has been key to these conservation successes, according to the conservation group.
