Bats fly through the night at Theodore Roosevelt National Park devouring flying insects.  Visitors can learn the "bat basics" from Erin Gillam, PhD, at 9 p.m. CDT on Saturday, August 29 in the Juniper Campground amphitheater in the park's North Unit.

Dr. Gillam, an assistant biology professor at North Dakota State University in Fargo, is doing bat research at both the North and South Units of the park this summer.  She is recording bat calls through portable sensors and capturing, tagging and releasing bats using mist nets.  She will be sharing the information she has obtained this summer and will give a general program about bats that live in the area.
