IMO, the best way to learn is to DO IT. If you can tag along with another experienced hunter then that is the best way. Shy of that, I think that reading books is better than watching vids.
When you do go into the woods, question everything. Why is this bed here, and not there? Why does this deer trail go along this slope and not the other? Why is this bush browsed and not the others? One question leads to another, and if you do it right you will NEVER run out of questions! When you question, then you LEARN. I've been in the woods for well over 40 years, and I still try to learn something new everytime I go out. It may be about animals, insects, plants, rocks, or even DIRT! It's all part of the whole.
I even learn from gutpiles. I always cut open the rumen (don't know what or where the rumen is? Get a book on deer anatomy and find out, because it's VERY important) on the deer I kill to examine the contents. I try to identify the tree or shrub species they've been browsing on, because the deer you just killed CANNOT LIE about where it just ate!
Get a good book on tree identification for starters, and learn how to identify all the main food trees that deer use, both in summer AND in winter. Your local DNR should be able to tell you what are the primary browse trees that deer in your area prefer.
Just simply being able to know the difference between Red oaks and White oaks can make the difference between a hunt being successful, and you not seeing a thing.
The more you know about the habitat that your quarry inhabits, the better the hunter you will be.
