A baby Buerger’s tree kangaroo appears out of her mother’s pouch at the San Diego Zoo in January 2003. The endangered species of tree kangaroo is native to Papua New Guinea. Hunted for food by indigenous communities across their Papua New Guinea range, the species has experienced a sharp decline in population numbers. The species is susceptible to an unlikely predator: domestic dogs.
