The main thrust of Dr. Whitaker's research is the ecology of small mammals.  Whitaker has made detailed studies on the food habits various mammals, herps, and fish, as well as helping to develop the technique used in analyzing insectivorous bat feces.  He has also devoted a great deal to the field of mammalian ectoparasites, helping to have described many parasites previously unknown to science.  Dr. Whitaker has contributed to  the natural history of many different organisms, with extensive work on shrews, rodents, salamanders, fish, and most recently bats.  Dr. Whitaker currently is studying the ecology of various bat species around the state, integrating radio-telemetry, food habits analysis, forage behavior, roosting habits, and ectoparasites to compile a new synthesis of bat ecology.  He is also working on various manuscripts and books, adding to his publication list that currently includes texts like Mammals of Indiana, Mammals of the Eastern United States, and the National Audubon Society Field Guide for Mammals.
