A Kenyan Wildlife Services veterinarian prepares to shoot a tranquilizer dart into an elephant at the Tsavo-East National park on March 19, 2012 during the second phase of a collaring exercise funded by International Fund for Animal Welfare and the Kenya Wildlife Services in the wake of a dramatic increase in elephant killings.
