From: Patch depletion, niche structuring and the evolution of co-operative foraging
Two types of grouping. Top: Traveling pairs (PAIRS): (A) traveling together; (B) depleting a patch together; (C) leaving a patch. Bottom: Opportunistic grouping: (D) arriving at a patch independently; (E) splitting up "zig-zag" fashion (OPP-GRa); (F) splitting up "bouncing" fashion (OPP-GRb), after leaving a patch. White squares: individuals; Black lines: trajectory of individual fading to dark green with time; Yellow: food patches; Dark green: background (empty space).
