This is the first of a two-course sequence exploring the main theoretical ideas and methods of ethology, the scientific study of animal behavior. In this first semester we explore the functional and evolutionary bases of animal behavior and cognition, exploring topics such as social behavior, foraging, territoriality and communication. Students will also learn and put into practice some of the ways that ethologists observe, record and measure behavior outdoors in the natural world. The main reading and discussion material for the course will be drawn from the first half of John Alcock's textbook, Animal Behavior, supplemented by journal articles from the professional scientific literature. Several summary/critique papers on the journal articles will be required, and a full-length term paper on a species and research topic of the student's choosing. The final project will be presented to the whole class either orally or in a poster session. Subsequent enrollment in the second semester of the sequence is encouraged but not required.
