Are there any animals that we have successfully brought back from being endangered?

Tons, actually in the US the endangered species act saved the alligator, bald eagle, California condor, wolves, and grizzly bear to name a few. In 1900 Buffalo were killed to the point of there only being 39 left until we started getting our shit together and protecting them in Yellowstone. Today there are over 75,000 buffalo with 60,000 on private lands and the rest on state and federal lands.

Edit: The condor is not off the endangered species list, but it is seeing a steady increase of population   every year.
