Stony, I have been a Deer and Hog hunter for more than 50yrs.
Most hunters don't care to know, all they want to know is when
and where to kill a deer in a short week-end. They no nothing about
the animal they hunt, only what it looks like.
I have been to many seminars on these subjects.

They should know the light spectrum of a deers eye ability. Ask any hunter
how the Tatum in a deers eye functions. Most don't know.
Every gland by name and locationon a deer and what they use it for. Most don't know.
Movements and vocalizations and what they mean.Most don't know.
etc.,etc.,etc.,......

Heck, I've even taken seminars on entomology, they show you many signs in
the deer woods.
You're on the right page Stony, keep learning as much you can on the animals
you like to hunt! Thanks again!
