Endangered species- Chatham island black robin

Chatham island Black Robin are

Definition: The black robin or The Chatham Island Robin is an endangered bird species from the Chatham Island off the east coast or new Zealand


What was wiping them Out: By 1900, The introduction of rats and cats following human settlement had wiped out the birds from everywhere apart from little Mangere Islands.When we introduced predators to the two islands where it presently survives is still a threat 
All black robins have the same weaknesses and strengths, stemming from the fact they have similar DNA. This means that a single disease could kill them.

How to help the black robin would be if you were to travel to the Chatham islands or transporting anything like food or livestock there, be careful that you don't accidentally introduce pest animals, plants or diseases. These might threaten the black robin or other rare endangered flora and fauna in the unique environment.

FACT: All of today's black robins are descended from the last breeding female, Old Blue. She was one of the longest-lived robins known, reaching 14 years old.

The story about how the Chatham Island black robin became endangered but then saved.

the total world population of Black Robins in 1980, And only one of them was a female.
