The month of April found me in Davis, CA, USA. I arrived at the Sacramento airport in California on the night of April 1 after a long flight from Entebbe, Uganda, via Amsterdam and Detroit. It was my first time traveling so far and visiting the USA. The flight was an experience filled with breath-taking views. I kept reflecting on how far away Bwindi and the Virunga Mountains were. My biological clock was switched 10 hours backwards! However, the month spent in Davis was worth the long journey and jet lag.
On April 2, Gorilla Doctors Co-Director Dr. Kirsten Gilardi at the UC Davis Wildlife Health Center oriented me to the campus and introduced me to the place where I would conduct my animal health training, the California National Primate Research Center or CNPRC. The center works with three species of monkeys: rhesus macaques, cynomolgus macaques, and titi monkeys.
During my month of training I worked alongside the Primate Center’s veterinarians and veterinary technicians, especially Stephen Cital-Bruhn, and was supervised by Dr. Kari Christe. I was able to participate in or observe all of the daily veterinary activities that happen at the CNPRC.
The CNPRC has two hospitals where the macaques are treated for health problems ranging from diarrhea and respiratory disease to trauma. I anesthetized animals for treatment; cleaned, sutured, and dressed wounds; and administered IV therapy and medications to sick monkeys. I observed surgeries as well.

I also attended necropsies and pathology rounds to discuss the different health cases at the Primate Center. I was able to appreciate how post-mortem exams are done at the center and learned some new techniques that will help me in the field.
Monitoring the health and behavior of the macaques living in the outdoor enclosures was another important activity. Each cage housed several macaque families and the monkeys were able to interact socially. The researchers helped me to understand the macaques’ hierarchy and the meaning of the animals’ different gestures, grimaces, postures, and sounds. Every day I checked for new babies (it was baby season) and carefully observed the macaques looking for signs of trauma or ill health. In April, all of the Primate Center’s monkeys were due for full health exams, so I was able to perform physical exams on many monkeys. During this time, animals received vaccines and deworming medication, had blood samples taken, and were tested for tuberculosis. Adult females were given pregnancy exams.
