Abstract

Squirrels (Sciurus sp.), Crows (Corvus caurinus), and Western Scrub Jays (Aphelocoma californica) are animals that exhibit optimal foraging behavior. To develop a field investigation that can be used by students in the BI 360 (Animal Behavior) course to investigate foraging methods of these local species, animals were presented with a variety of nuts, both with and without shells, in various combinations to see what food preferences they have. Pre-weighed nuts were placed out in trays for variable amounts of time and periodically observed for visits by target species. Following observation periods, nuts were re-weighed. I will be developing field protocols to include experimental and data collection techniques that will enable future WOU Biology students to demonstrate optimal foraging behavior in these easily observed species.
