Why is relying on a rat snake's mere presence to deter a copperhead usually unreliable?
Answer
A snake is unlikely to advertise its presence to a potential predator unless cornered or threatened.
The deterrence effect of a rat snake's presence is considered indirect and unlikely because snakes generally do not announce their location to potential threats unless actively challenged or cornered.
