ANSWER: Feeling confident, aren't you? Antler characteristics can identify yearling bucks, and perhaps 2 ½-year-olds, but the only way to field judge older bucks is to look at their bodies. Their chests get deeper, their bellies sag, and their faces look, well, older. But it takes considerable skill and experience to become proficient at classifying their ages. The Quality Deer Management Association (www.qdma.org) has a couple of resources that can help you immensely. First is the just published book Observing and Evaluating Whitetails by Dave Richards and Al Brothers. It offers thorough explanations of aging and scoring whitetail bucks and the dynamics of antler development, and lots of pictures. Second is A B&C Club Field Guide to Measuring and Judging Big Game by William Nesbitt and Philip Wright. The QDMA also has published a poster, "Selective Buck Harvest," which would be excellent to hang at your hunting camp.
