How come deer run for their lives when they hear a branch crack but will gladly wait in the middle of the road for a +100kph hunk of metal
In: Biology
Broken branches are noises they understand to be bad. Road noise is background noise in most cases and so when they hear a louder version of it, they do not know what it means.
Similarly, a huge moving object with no visible legs is not immediately a threat since the predators they deal with a smaller than they are: they have no understanding of “big = bad” so do not have an immediate flight impulse.
