His body says 4.5 and face says 3.5. I think it is really impossible to tell the age of deer after age 3. The only way to know for sure is if you have history with the individual deer. Anyone that says they know the age of the deer 100% accurate without history is full of well you know. I know guys that do this for a living and they will tell you it is just an educated guess. Deer are no different than people some are tall, short, skinny and fat. It is all a guessing game after 3.5 yrs old IMO. I am guessing if you run several camera's every year and haven't got his picture before then he is a 3.5 and you probably have his picture at 2.5 but never grabbed your attention.
