Comeback Species

1. American Bison- Before colonists there were over 30 million roaming north America. Eventually they were hunted to the point where only 750 were left. Thanks to breeding programs and reserves their population is up to 80,000.


2. Kiwi Bird- The New Zealand mascot has been under legal protection since the 1800s. The program has raised the chick survival rates from 5 to 85%!

3. American Alligator- more than half of all alligator/crocodile species are endangered, mainly due to hunting for their skins. However thanks to protection plans they have recently made a comeback.

4. Black Robin- In 1980 there were only 5-7 black robins known in the world, and only one pair was mating. Today there are 250, still not a lot but on their way to recovery.

5. California Condor- In 1981 there were only 21 living in California, and by 1987 the last wild one was caught and placed in a breeding program, their current population is estimated to be around 200.
