Foraging Behavior - The Search for Food

Optimizing its foraging behavior

1. When the difference between the energetic benefits of food consumption  and the energetic costs of food gathering is maximized.

2. Animals with optimal foraging strategies will have more available energy with which to survive and reproduce.
