I am a self taught hunter and before the internet you could buy books to read for more in-depth information than a hunting magazine. Dr Ken Nordberg wrote a series of books on whitetail, I read them all. Back before trail cameras you had to have to look for sign. One of them was bedding areas and single beds. Mature buck droppings tend to be clumped while does and fawns are pellets. You find a bed with clumped poo that is a buck bed. I was at the public library this afternoon Mr Stan Telila did a presentation on deer moose and elk. It was a question I asked and he answered. It was very interesting evidently spotted fawns during gun season is become more widespread.
I'm very much self taught too, since none one of this tech was around in the mid 70's when I started deer hunting. I read books and magazines to learn the basics, and boots on the ground filled in the gaps. I prefer to use non-cell cams, because you have to physically go into the woods to check them. This is when I look for the sign, especially during the rut (scrapes, rubs, trails) that doesn't show up on trail cams, which really only show what's going on in one specific spot. I have seen some clumped deer poop and wondered why it wasn't the usual pellets we see most often. I didn't know it's often a buck that left them. I'm never done learning. Good info.
I have personally witnessed both sex of whitetail poop while hunting. The big clumped piles were always from the bucks. Most of the does were individual pellets, but I have seen does that are on green feed have some clumping also..
