“These three birds are over half the world population of their species.” Peter Hayden’s narration lays bare the stakes for the Chatham Island black robin, and the Wildlife Service team (led by Don Merton) trying to save them. Merton’s innovative methods include removing eggs from nests – to encourage the last two females to lay again – and placing them in riroriro (grey warbler) foster homes. The black robin documentaries helped forge the reputation of TVNZ's Natural History Unit. Paul Stanley Ward writes about the documentaries here, and the mission to save the black robin.
Despite all the experiments, Don doesn't know if the warblers will accept a robin egg. It seems highly risky to hijack Old Green's precious clutch.– Narrator Peter Hayden
