Filmed on Whenua Hou/Codfish Island, this episode of long-running series Wild South examines the secretive lives of the kākāpō and their most successful breeding season in 16 years. Though these lovable parrots are notoriously slow-breeding, a 52-person recovery team pulls out all the stops — including spy cameras and robo-birds — to help the adult birds canoodle as much as possible, and keep the resulting chicks alive. When the episode starting filming in 1998, there were only about 50 kākāpō left. Since then, that number has more than quadrupled, but the kākāpō remains one of the world's most endangered birds.
