Forager is designed to be an easy-to-use, comprehensive foraging behavior model. Forager supports hierarchical matching, marginal value theorem, dynamic programming, and predator-prey models. Users can design foraging habitats, play back model runs to see how animals move through the environment, and create publication quality tabular and graphical output.
