Rodents in open space adjust their behavioral response to the different risk levels during barn-owl attack.

ABSTRACT: BACKGROUND:Previous studies have revealed that the response of prey species to predatory risk comprised either freezing (when the prey remained immobile), or fleeing (when it ran frantically in order to remove itself from the vicinity of the predator). Other studies, however, have suggested that the prey will adjust its behavior to risk level. The present study was designed to follow the attacks of a barn owl (Tyto alba) on common spiny mice (Acomys cahirinus) and social voles (Microtus socialis guntherei), in order to reveal the correspondence between the behavior of the owl, the risk level at each phase of the owl's attack, and the defensive behavior of the rodents. RESULTS:Spiny mice dramatically increased the traveled distance upon the appearance of the owl, and kept moving during its
