Rattlesnake foraging behaviour. (a) Time spent over the scent stimuli and their water controls and (b) total tongue-flick counts over the scent stimuli and their water controls. Rattlesnakes spent more time and tongue-flicked more over all three scent types than their water controls (all p<0.05). Rattlesnakes spent more time over squirrel scent than squirrel+rattlesnake and rattlesnake scent (p=0.048 and 0.042) and tended to tongue-flick more over squirrel scent than squirrel+rattlesnake and rattlesnake scent (p=0.070 and 0.030).
