In　recent　years,　an　increasing　number　of　studies　have　focused　on　exploring　the　principles　and　mechanisms　underlying　the　emergence　of　collective　intelligence　in　biological　populations,　aiming　to　provide　insights　for　human　society　and　the　engineering　field.　Pigeon　flock　behavior　garners　significant　attention　as　a　subject　of　study.　Collective　homing　flight　is　a　commonly　observed　behavioral　pattern　in　pigeon　flocks.　The　study　analyzes　GPS　data　during　the　homing　process　and　utilizes　acceleration　information,　which　better　reflects　the　flock’s　movement　tendencies　during　turns,　to　describe　the　leadership　relationships　within　the　group.　By　examining　the　evolution　of　acceleration　during　turning,　the　study　unveils　a　dynamic　leadership　mechanism　before　and　after　turns,　employing　a　more　intricate　dynamic　model　to　depict　the　flock’s　motion.　Specifically,　during　stable　flight,　pigeon　flocks　tend　to　rely　on　fixed　leaders　to　guide　homing　flight,　whereas　during　turns,　individuals　positioned　in　the　direction　of　the　flock’s　turn　experience　a　notable　increase　in　their　leadership　status.　These　findings　suggest　the　existence　of　a　dynamic　leadership　mechanism　within　pigeon　flocks,　enabling　adaptability　and　stability　under　diverse　flight　conditions.　From　an　engineering　perspective,　this　leadership　mechanism　may　offer　novel　insights　for　coordinating　industrial　multi-robot　systems　and　controlling　drone　formations.　©　2024　by　the　authors.
