The scenario I'm talking about is *mountains* and mule deer.
Migration is to avoid the killing snows. They migrate up and
down the mountains.

I'm just citing a local EIS (paid for by the
prospective dam builder). Part of the supposed
mitigation was trash gards on the water intakes, and
a deer path on top of the 300 foot tall dam.

Sorta like New Yorkers migrate to Florada when
they retire? Perhaps into a condo with the deer
that already live there? You have much to learn
about deer and ecology.
If an ecologist goes deer hunting, it's not
hunting, it's meat harvesting.

Assuming they had human intelligence, rather than
instinct, to where? Have you ever wondered why
a certain deer population (or any wild animal) has
that population number? There is no place to move,
if there was a "good spot," it would already be full.
