What to do when the wild gorilla has the flu? Time to send for a field veterinarian like Dr. Felicia Nutter of Rwanda’s Mountain Gorilla Project. This vet makes jungle calls, tracking down and treating the ailing gorilla in the wild. Long endangered because of poachers, rare gorillas of Rwanda are now even more endangered from diseases contracted from humans and other animals. This title in the Scientists in the Field series introduces a new breed of field veterinarians, epidemiologists and public-health workers, meeting the challenge with up-to-date technology and dedication. The author, who has a degree in public health, is especially successful in explaining how improving community public health benefits both gorillas and humans. Spectacular and appealing photos of gorillas, scientists and the Rwanda Preserve add even more appeal. An outstanding science nature title.
