Critically endangered. Bali mynahs are nearly extinct in the wild because poachers collect them for the illegal pet trade, where they are valued for their striking plumage and beautiful songs. Because of this poaching, Bali mynahs are found almost exclusively in zoos. Scientists at Lincoln Park Zoo help conserve Bali mynahs by keeping the studbook for the species. Studbooks contain the family trees of every individual animal in the zoo population. By pairing animals that are distantly related, zoo scientists can help ensure that offspring are genetically healthy. Lincoln Park Zoo participates in the Bali Mynah Species Survival Plan®, a shared conservation effort by zoos throughout the Association of Zoos and Aquariums.
