What advise would you give to a new deer hunter?
This will be my first season deer hunting.
I will be hunting on invite only as I do not own/lease any land. What is a customary thank you for a land owner?

My rifle is sighted in so that can be crossed off.

1. Respect their property as if it were your own. Most important one. If they have a great place to hunt, it was made that way by somebody's hard work, perseverance and respect for the outdoors.
2. Respect their wishes as to management practices. If they only shoot 8 point or better outside the ears, make sure you exceed their expectations. If they say they only shoot trophies, make sure it is something you are willing to fork over the nearly $500 it will take to mount it. If they are like us and encourage the shooting of does to help in population control, don't pass up the chance to kill a doe. Unless they request it, don't shoot a young buck.
3. Offer them at least a backstrap if you kill a deer. A backstrap and hindquarter would be more in line.
4. Offer to help with any work that needs to be done.
5. Pick up any litter you see on the property whether you put it there or not.
6. Don't show up as a know it all. If you haven't hunted Bama, you will learn that our deer are well educated and smart but plentiful. Listen to the oldtimers. You'll hear some crazy stories about what a smart old buck will do and more times than not the story is rooted in truth.

DONT GO PIDDLING!

So far it seems fairly straight forward.
Be polite,use common sense and do as I am told all of which makes sense to me.

That means purposefully & knowingly snooping, trespassing, or poaching on property that isn't yours correct?

like jawbone said, go out of your way to do something for landowner with out being asked. Move a blown down tree out of the road, pickup trash, etc. Always mind gates and roads - never drive in fields. Always say thank you. Offer to help with any work - you might get an invite back

And don't go piddling. Stay where you are offered a place to hunt

If there are woods roads keep some loping snips and prune back the limbs in the roads, it won't take long and it is something that almost all roads need. If they have a work day(s) show up and offer to do anything, it is the best way to learn the property without appearing to joy ride.

Thats a good idea. Clean up the roads to make it better.

All solid advice here. If you will be hunting in an area alone be sure that you are on the same page with the people who invited you, in terms of where they want you to go and when you need to come out. Stay in your stand or area and don't get up and wander. A sure fire way to not get invited back is to get antsy and go "scouting" while others are in their stands.

Being respectful and willing to earn your keep, as others have mentioned will go a long way to getting invites to go back..

Also if you find you enjoy deer hunting and really want to go, there are thousands of acres of public land around your location that your license pays for.. If you can find and kill deer on public ground, you can kill them anywhere..

When hunting on public land is it acceptable to use a ground blind?
Seems like that would be less than ideal because of others with itchy trigger fingers around.

My best advice is don't shoot the first deer you see. Watch them. Learn to read their body language. You can learn to tell when they are spooked and likely to bolt away. As a new hunter, you need to study them and learn to tell the difference between a doe and a spike with 1" nubs. Most spikes are killed being mistaken for does. You can tell the difference by looking at the shape of the head. A bucks head will appear flatter across the top due to his pedicles. A does head will be more rounded. There is no better teacher than observing live deer in the wild.

The studying & patience part is really good advise.
I plan on loading my magazine but keeping it in a pocket to help with the self control of looking but not shooting.

Listen to hunters who are successful and don't buy into most of what you see on the outdoor channel.

Observe , observe and observe some more.

Pay attention to detail.

When you see a buck, take the first shot he presents you can make.

forget about "killing a deer" and just learn to enjoy the outdoors, you will be alot more sucessfull. There's a whole lot going on out there that most folks miss. Like why did the squirlls all get quit, what made that rabbit run accros the food plot. Get comfortable, be still, and be patient. Visualize what your gonna do when the deer comes out. Move slow if the deer can see you, and freeze if they look at you, usually they'll go back to feeding. You can hunt all season for them few seconds at a shot at a good deer, and mess it up by bumping the gun against the stand or clicking the safety. Before season I do some target acusition drills. Just find a target and practice aiming at it. But most importantly have fun and the deer killing will come.

I wouldn't recommend that personally. There's no way you'll ever be able to load your rifle quiet enough, should the need arise. Just use self control. Tell yourself you will only shoot "X" and stick to it. One I haven't seen listed to make 100% sure you exercise firearm safety at all times. The quickest way to never be invited back is to make someone feel like you are dangerous.

That makes sense. Well then that brings up a good question, assuming the land owner doesn't place limitations, what should I consider X to be, for buck I am thinking nice 6 point.

The safety point is a good one.

For processing how does that work usually. I assume you drop the deer off field dressed, for payment do they keep a percentage of the meat or is it cash only?

Is tipping customary in the hunting world for things like taxidermy or processing?

I would ask the person inviting you what their harvest criteria are. Like another poster suggested, make sure you exceed those expectations. Some folks are fine with shooting yearling does, some only want mature does shot. The quickest way to not be invited back is to take a deer that doesn't fit their criteria. This is very subjective depending upon the people you're hunting with, but it's a reality of the situation. If you were a dues paying member of a club, you could rightfully take any club legal deer. As a guest, you need to abide by rules that are written and unwritten. Making sure you exceed their expectations is the unwritten part.

Yes, processors are generally cash only. I do not know of any that accept meat as payment. They are not legally allowed to sell the meat to the general public as it has not been subject to federal inspection like commercially sold meat. They are supposed to process the animal only for the person bringing it in. Some processors will gut the animal for you but generally charge an extra fee. Most of them prefer you to bring it in field dressed because most processors have limited space for disposal and they can fill a dumpster up when they get real busy.

Get the guts out ASAP. Decomposition starts as soon as the animal is no longer living. The bloating you see on dead animals is the bacteria inside the animal giving off gases. This will affect the taste of the meat if you don't remove the guts promptly. You will read many different opinions on the proper way to handle your venison. I suggest you buy a book called The Complete Venison Cookbook and read. He describes every step you need to take from field to table. It's very informative.

I will be asking lots of questions to the owner before ever entering the woods. I don't want to shoot ole nasty tines who he was saving for ____ to hunt.

Get the innards out ASAP. That makes sense.

What about stand suggestions? I am not a fan of the cold so I plan on bundling up like the Michelin Man. Any tricks to staying warm and keeping quiet?

as above...
4. Offer to help with any work that needs to be done.
5. Pick up any litter you see on the property whether you put it there or not.

If I invite you, I want you to go home with a deer. I personally hunt because I like the meat. I want you to take home your meat. An offer is appreciated, but I will turn it down. Just me. If you feel inclined, a six pack or bottle of bourbon to show your appreciation is always accepted!

Biggest thing is, ask/know/respect the harvest rules. Again, my place (small) all is fair game. Most are passing through. But others have very strict harvest requirements.

And last, treat the place and rules, etc as if they were your own. Someone has spent a lot time effort and $$$ to have a place that they can invite you to hunt!

Go and HAVE FUN!
