How about this dude? This one should not take long, right?
Aging this Buck from a Camera Photo
I see a very young buck. This is actually a 1 1/2 year old buck with his very first set of antlers. Bucks that are 1 1/2 years of age appear smaller than adult does. Using antler size to age young bucks is actually quite effective most of the time.
Rarely will there be middle-aged or old bucks running around with such tiny antlers. This guy would be off limits in my book. Give him at least another 3 years before putting a tag on him.
