The Black Robin or Chatham Island Robin (Petroica traversi) is an endangered bird from the Chatham Islands off the east coast of New Zealand.The Black Robin is a sparrow-sized bird measuring 14–15 cm . Its plumage is almost entirely brownish-black, with a black bill and brownish-black yellow-soled feet.
The species is still endangered, but now numbers around 250 individuals in populations on Mangere Island and South East Island. Ongoing restoration of habitat and eradication of introduced predators is being undertaken so that the population of this and other endangered Chatham endemics can be spread to several populations, decreasing the risk of extinction by natural disasters or similar stochastic events.
