Chatham Island black robin

The Chatham Island Black Robins are small, black, sparrow sized birds. Their native to the islands of the coast of New Zealand. The humans brought forth cats, rats, and other non-direct forms of hurting their population. Before long almost the entire species became wiped out. By 1976 only 7 birds remained alive. Instead of trying to breed them in captivity they brought them to a preserve and procted their species. Success was not immediant, four years later no babies were hatched and two of the birds died leaving only five. Their were only one breeding pair left. The small black robins only lay one cluth of eggs per year, but like the condor they will lay more if one or both are lost. So scientist gave robin eggs to surrogates for hatching- though this time, surrogates were of a different species. The unusual program worked. Vurrently theier are over 250 species of black robin in the world.
