US researchers led by Dr Vladimir Dinets from the University of Tennessee have found that two croc species – mugger crocodiles (Crocodylus palustris) and American alligators (Alligator mississippiensis) – use twigs and sticks to lure birds, particularly during nest-building time.
Their study, published in the journal Ethology, Ecology and Evolution, is the first report of tool use by any reptiles, and also the first known case of predators timing the use of lures to a seasonal behavior of the prey.
