2013 Study Claimed Crocodilians Use Sticks as Bird Bait, but Evidence Remains Disputed

Summary
A 2013 paper reported mugger crocodiles in India and American alligators in Louisiana balancing sticks on their snouts near bird colonies, especially from March to May when nesting birds seek twigs.
That pattern suggested reptiles might be deliberately baiting birds, potentially marking the first reported tool use in any reptile, but the key step—intentional placement to lure prey—was rarely observed directly.
A later experiment at 4 Florida parks found captive alligators did not consistently match the baiting hypothesis, yet that study was later withdrawn and its authors said captive settings were a poor test of wild hunting behavior.
What remains well supported is narrower: crocodilians are sometimes seen with sticks near rookeries during nesting season, and birds approaching for nesting material can be attacked; whether that qualifies as true tool use is still unresolved.
