A single black robin named Old Blue saved her entire species

The black robin or Chatham Island robin is an endangered bird from the Chatham Islands off the east coast of New Zealand.

A black robin named Old Blue has become the mother of her entire species when she was the last fertile female in a group of 5 robins on the Chatham Islands. She has helped raise their status from critically endangered to endangered and there are now 250 black robins.

Survivorship between 1980 and 1991 indicates a mean life expectancy of four years. “Old Blue” however, the sole breeding female in 1980, lived for over 14 years.
