I have seen him multiple times the previous two seasons, and believe he is a 5 yo.
So, the reason I wanted some estimates on this guy is because his headgear shrunk from last year. He has less overall length, and definitely less mass. Overall antler size, I'd guess he's about the same as he was as a 3yo.
Could it be a nutrition issue? It's powder dry now and we haven't had any real measurable rain since we got a really good 31/2 inches in early July, which filled tanks and kept everything green through early August.
I know this is the same buck, the only thing new is the big sticker off his right side base, but there is no mistaking the ear.
