No matter what time of year you are using cameras to observe deer activity, the main goal is still the same for most hunters. That goal is to gain enough information to give the hunter an edge at harvesting a mature buck during the hunting season.
When in velvet, antlers are very vulnerable. Bucks are intuitively aware of this and are very careful during the growth process. This is one reason it’s common to see bucks out in the open when they are in velvet.
