I have been paying a lot of attention to ballon’s over the past few years. I think I could put the same comment in every deer thread on the forum: deer behavior and their relationship to the landscape varies across the country. While there are behaviors and qualities common to whitetails anywhere, there is also huge variability. This can make conversations on a forum like this cumbersome.
No matter where you hunt, ballon’s are often a great indicator of dropping thermals and eddys in wind currents. In the hills and small mountains where I do most of my hunting ballon’s are sometimes found near bedding, and more often balloons are associated with evening and nighttime staging areas for all deer, cruise routes just off wind on leeward slopes, and also low spots where bucks scent check leeward basins. On many ocassions I’ve seen a bumped deer run to basins where ballon’s collect to take stock, presumably as a way of reading the landscape - to determine where there is pressure and where there are safe escape routes, etc etc. So at least in my region balloons provide all kinds of information but rarely are a one to one correlation, they have to be put in context.
