Predator mobbing behaviour in the Greater Spear-Nosed Bat, Phyllostomus hastatus
Knörnschild, MirjamTschapka, Marco
We report that several adult Greater Spear-Nosed Bats (Phyllostomus Hastatus, Phyllostomidae) extensively harassed a large spectacled owl (Pulsatrix perspicillata, Strigidae) for several minutes. We hypothesize that the bats considered the owl to be a petential threat because it was perched in close vicinity of the bats night roost. To our knowledge, this is the fist direct evidence of predator mobbing behaviour in bats.(AU)
