Stimulus control of predatory attack in the brown tree snake (Boiga irregularis)
Keyword(s):
AbstractThree experiments studied predation upon neonatal rodents by brown tree snakes (Boiga irregularis). Experiment 1 showed that chemical cues arising from prey were used in foraging tests that could not be completed on the basis of vision alone. Experiment 2 provided only airborne chemical cues, and snakes performed at chance levels in selecting among odoriferous (baited) and non-odoriferous (unbaited) nests. Snakes performed above chance, however, when a chemical trail led to the baited nest (Experiment 3), suggesting that non-volatile chemicals are most important in guiding choice behaviour.
