Using objects as hunting lures is very rare in nature, having been
observed in just a handful of species. We report the use of twigs and
sticks as bird lures by two crocodilian species. At least one of them
uses this method predominantly during the nest-building season of its
prey. This is the first known case of a predator not just using
objects as lures, but also taking into account the seasonality of prey
behavior. It provides a surprising insight into previously
unrecognized complexity of archosaurian behavior.
