The recorded history of the California condor, unfortunately, is similar to that of various other birds that have been decimated by man in recent decades. The species formerly ranged throughout the west from British Columbia south to Lower Califor- nia, and eastward to Alberta and New Mexico. Fossil remains from St. Petersburg, Florida, indicate an even wider distribution in prehistoric times.
