Field classes meet for an entire day at a time, typically between breakfast and dinner. Some classes (e.g. Biology of Birds) start before breakfast and finish in the early afternoon. Others (e.g. Field Mammalogy and Biology of Fishes) may occasionally meet in the evening or even overnight. These extended class periods give you a chance to visit and spend time learning about sites away from campus, as well as collect data or run small experiments there.

These classes take place at the Biological Station in a 4-week spring session (Spring), and an 8-week summer session (Summer). Open to students from any college or university.

These two-part classes have a regular lecture component in Ann Arbor during fall or winter semester and a field component based at the Biological Station in spring or late summer. Open to U-M students only.
