I've been thinking about this recently and was wondering if anyone else can put me right.
What is a deer's strategy for escape? I would guess that deer have evolved a strategy which ensures that they make the best of any chance to escape from a predator (that's me in the funny clothes trying to get the rifle off my back with one of the bipod legs stuck in a coat pocket) and that they probably apply when bumped by a stalker. As an example I've noticed that sika when you actually bump them by frightening them and they are sure you've seen them tend to run without any worry for the noise etc. but after a short distance they seem to slow up and then make a cautious, quiet disappearance. However, if they think you haven't seen them they will attempt to sneak off without giving you the chance to spot them. On the other hand sometimes, even when they are sure you've seen them, they will sit tight and just watch you and I suspect this mostly happens if they spot you first and have time to evaluate the threat before they think you've seen them.
Does anyone know how they select a strategy for escape and if they have a fixed menu of escaoe routines?
