preforaging

Preforaging is a term used in ecology to describe the preparatory phase that precedes active foraging. It encompasses the behaviors and cognitive processes used to locate, evaluate, and map resources, as well as to assess risk and energetic costs before direct resource collection begins. Preforaging is typically distinguished from foraging by its emphasis on scouting and information gathering.

Typical components of preforaging include habitat assessment, travel planning, resource mapping, cue sampling, and risk appraisal. Organisms may exhibit scouting movements, environmental sampling, and social information sharing during preforaging. The duration and intensity depend on habitat complexity, resource distribution, and energy needs.

Across taxa, preforaging has been observed in birds, mammals, insects, and humans. In marine systems, predators may patrol areas and monitor prey signals before attacking; in terrestrial settings, individuals may fly, walk, or scent-mark to acquire information that will guide later exploitation.

Research approaches include tracking movement with GPS or accelerometers, behavioral sequencing, experimental manipulations, and modeling of search strategies. Understanding preforaging helps explain how organisms reduce search costs and improve the efficiency of subsequent foraging.

Critics note that the boundary between preforaging and foraging is not fixed and may vary by context, making strict categorization difficult. The concept remains debated within foraging theory and cognitive ecology.
