While all that's going on in the field, the heart of the organization actually centers around the Orphans' Project, which brings us back to the baby elephant whose trunk introduced itself to my cheek. The project, which is the most successful of its kind, has rescued and raised more than 170 baby elephants, and then reintegrated them back into the wild. During my visit, 55 keepers were caring for 77 elephants, many of which are infants. This is the most elephants than the Project has ever had. The keepers feed them a special milk formula, developed on the premises, for the first three years of the animals' lives, while also working to heal them, mentally and physically. The cost to care for each elephant is about $900 a month -- raised from donors -- and an elephant remains at the center for five to 14 years, until it's ready to be released into Tsavo National Park.
