Table 2 Activity times and flight behavior of 435 cane toads (Rhinella marina) at six sites (gorges) with different physical attributes. For gorge width W = wide, N = narrow. For gorge axis N-S = north-south, E-W = east-west. # fleeing = upon approach by the observer to 0.3 m away. EG = Emma Gorge, EPP = Emma Gorge Plunge Pool, GBG = Ghost Bat Gorge, AG = Amalia Gorge, ELG = El Questro Gorge, MG = Moonshine Gorge.
