Jennie, Another good book that gives an entertaining and enlightening look at the condor conservation breeding program is "Condor: To the Brink and Back" by John Nielsen. You can find it here: http://www.amazon.com/Condor-Brink-Back-Times-Giant/dp/006008863X/ref=pd_bbs_3?ie=UTF8&s=books&qid=1235074559&sr=8-3
Enjoy! -Matthew Erdman
