“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.
Once again, the stakes of Merton's field experiments could scarcely be higher.– Writer Paul Stanley Ward, in his backgrounder on the black robin documentaries
