The long-tailed koel is a bird from the cuckoo family with a very long tail. It inhabits the islands of the Pacific Ocean and lays its eggs in the nests of other birds.
The long-tailed koel stands out with its very long tail and the fact that it does not build nests. As a brood parasite, it affects populations of small birds and helps control insect numbers on the islands.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
