Testing Optimal Foraging Theory Using Bird Predation on Goldenrod Galls
Yahnke, Christopher J.
American Biology Teacher, v68 n8 p471-475 Oct 2006
All animals must make choices regarding what foods to eat, where to eat, and how much time to spend feeding. Optimal foraging theory explains these behaviors in terms of costs and benefits. This laboratory exercise focuses on optimal foraging theory by investigating the winter feeding behavior of birds on the goldenrod gall fly by comparing disturbed versus undisturbed galls, and by comparing gall densities in different goldenrod patches.
