How old do you think this buck is? Also, it seems like he can see the camera and it's made him a bit nervous. I'm worried that my cameras are spooking deer and they might avoid the areas where I put them. I have a couple of videos of deer running away when they see my camera, makes me wonder if I should take them down.

thats a nice buck. Id say 3.5. It was hard to tell. I couldnt see his body size to tell if he had a sagging belly. Still a nice buck. I really liked his antlers...

I am going to go with 3.5 too.

This angle in the summer is extremely hard to judge. However, his body is full enough to give him at least 3.5. Also, the mass that he carries throughout the tines (even though he's in velvet it's clear he has mass in his tines) makes him at least 4.5. I doubt he is any older but again this is a tough angle to judge.

I would have to go with 3.5 but he could be 4.5

I would go with 3.0. He is a nice buck, next year either way, he will be a beast. his face and growth makes me believe he is a little younger that 3.5 with really good genes. I don't know if I could pass on him this year though.
