Closed 31 Oct 2026 Internship

Internships and training opportunities are centered on training and provide support towards stipends and possibly living costs.

The opportunity

Training in non-invasive field research, on a long-term study of rhesus macaque physiology and behaviour. Interns join the team on the island on weekdays, observing the free-ranging monkeys and collecting behavioural data and faecal and urine samples. Those who can stay from early January to early October 2027 are preferred.

What it involves

  • Observing adult and juvenile monkeys in their natural habitat and recording their behaviour
  • Collecting faecal and urine samples non-invasively, as the chance arises
  • Weekdays on the island, about 7.5 hours a day

Who can apply

  • US citizens and permanent residents aged 18 or over
  • Able to spend most of a long day on your feet in heat with little shade, on steep and uneven ground
  • At ease close to free-ranging monkeys, with the alertness wild animals call for
  • Comfortable collecting faecal and urine samples
  • An interest in biological anthropology, animal behaviour, primatology, ecology, veterinary science or a related field
  • Independent, and a good member of a team
  • Before starting: proof of diphtheria/tetanus and two-dose MMR vaccination, a negative TB test from the six months before the start (a blood test preferred), negative measles titres (IgG), and a health questionnaire
  • Preferred: field experience, especially with primates or in hot climates; a bachelor's degree in biology, anthropology, ecology or a related field; basic Spanish
