I would like to thank the scientists who made this book possible: Samuel Andanje, Thomas Gnoske, Dr. Julian Kerbis Peterhans, Ogeto Muwebi, Dr. Craig Packer, Dr. Bruce Patterson, and Peyton West. Thanks also to the staff of the Kenya Wildlife Service, to Wayne Hosek, and especially to my editor, Steve Byers, for all the angst and Sturm und Drang he endured on my behalf.
