The Smithsonian Institution encourages access to its collections, staff specialties, and reference resources by visiting scholars, scientists, and students. The Institution offers in-residence appointments for research and study using its facilities, and the advice and guidance of its staff members in fields that are actively pursued by the museums and research organizations of the Institution.
At present these fields include:
- Animal behavior, ecology, and environmental science, including an emphasis on the tropics
