Your right about the maybe bumping them out but it's ok for them to sneak up on you. They are very relaxed in the thick stuff and will usually wonder around. That's why shooting lanes only have to be small areas/holes. That's probably the biggest thing you will doubt yourself on when getting up a tree in the dark. You'll be ok. From the air things have a way of opening up for you. I reccomend you try it once and find out. It may surprise you.
