The magnificent California condor has the largest wingspan of any North American Bird, reaching up to 9.8 feet. Unfortunately, this species is critically endangered, and conservation efforts are working hard to bring them back from the brink of extinction. However, they can still be found in parts of California, Arizona, Utah, and Baja California in Mexico.

The recovery of the American Bison population is an example of successful conservation. Their population has made a significant comeback with strict conservation measures that have brought them back from the brink of extinction. They can be spotted in Yellowstone National Park and the National Bison Range in Montana.
