Searching for food. Foraging in natural habitats has been treated as a chain that includes search, prey identification, capture of prey, and handling and/or consumption of prey, with concurrent or concurrent-chain performances treated as analogous into parts of this chain (e.g., the foraging patterns according to which organisms switch from partially depleted patches of food to fresh ones can be characterised in terms of strategies examined within concurrent performances, such as matching, momentary maximizing, and optimizing).
