Harvesting white-tailed bucks based on age is ending up being an increasingly typical management strategy. To implement this practice, hunters must have actually the capability to accurately period bucks on the hoof based on their human body characteristics, an capability that most hunters taken into consideration impossible a te ago. This particular day however, hunters throughout the whitetail’s selection are estimating the period of bucks in the ar as a way for selective harvest within top quality Deer management programs or merely for the fun of it.

Like humans, whitetails possess unique body characteristics by period class, and with a little practice hunters and also nonhunters alike can end up being proficient in ~ estimating the age of bucks ~ above the hoof. There are many great reference books, videos and DVDs obtainable for thorough instruction and practice top top aging bucks, and also this write-up serves to present the topic and also highlight the differences for each age class from fawns come post-mature animals. This body qualities are topic to differing interpretation by various viewers, however the features are family member to rather in her area or region. Body characteristics also change by season. The breeding season is the best time that year to period bucks because of pronounce neck swelling and tarsal staining. You have the right to estimate their period at various other times that the year, but many attributes are perceived relative come what they will certainly (or did) look at like throughout the rut.


Fawns space easily identified from other age classes the bucks but are frequently misidentified together female deer. Buck fawns have little square bodies, tiny short heads and relatively big ears. Their heads space flatter between the ears quite than rounded like that the a doe. The street from their ear come eye is likewise approximately the very same as the distance from your eye come nose. In contrast, the street from an adult doe’s ear to eye is much much shorter than native its eye come nose. Fawns additionally have short necks, flatter bellies and also backs, and less muscle meaning than adult does. QDMA has developed an educational poster, identify Antlerless Deer, that uses close-up photography that live deer to assist you find out to kind fawns native adult does and also buck fawns from doe fawns using these characteristics. This renders a good visual tool for teaching hunting-club members or guests how to stop harvesting buck fawns.

1½ years

For most QDM programs, specifically those in start stages, learning to determine yearling bucks is the most vital aging skill. Yearling bucks have actually long legs, a slim neck, a slim body and also an in its entirety lanky appearance. Your legs appear too lengthy for your bodies due to the fact that their torsos (stomach, chest and neck) space not completely developed. Your antler spread is virtually always much less than the broad of your ears once their ears are in an alarm position. They have actually a unique line that separation between their neck and also shoulders and tiny muscle definition. They have a thin waist, and also they may have actually slight staining in your tarsal glands throughout the rut. Overall, a yearling buck have the right to be stated to look like a doe through antlers. In well-managed populations on high-quality-habitat, yearling bucks deserve to have big bodies and also even 10 or much more antler points, however the above characteristics will be present and also can be used to different them indigenous 2½-year-olds. This is why the is important to examine body characteristics prior to considering antler size once attempting to age a buck in the field. 

2½ years

Two-year-olds have actually legs that still show up too long for your bodies, and also they still have actually an in its entirety sleek appearance. They have arisen some muscling in their shoulders and also slight ede in their neck throughout the rut, however their waist is quiet thin. Offered adequate nutrition, their antler spread can be equal to or wider than their ears. Finally, they have the right to have moderate staining in their tarsal glands during the rut, specifically if few mature bucks are in the population.

3½ years

Three-year-olds have actually legs that show up to it is in the right size for your bodies because their torsos are currently more completely developed. They have actually muscled shoulders and a extremely swelled neck throughout the rut, yet their waist is quiet lean. I liken three-year-olds to center linebackers together they are large and solid but they’re also lean and fast. A deep chest and also lean waist give them a “racehorse” appearance. Their antler spread deserve to be also with or broader than your ears. Research mirrors that in ~ this age, most bucks have completed 50 to 75 percent of your antler-growth potential. They additionally have a lot of tarsal staining during the rut.

Beyond 3½ year of age, determining the exact period of a buck i do not care more complicated because of enhanced variation among individual bucks. However, for many QDM programs, harvest goals have the right to be accomplished if hunters space able to confidently separate bucks into one of three groups: A) Yearlings, B) 2½-year-olds, and also C) 3½ or older. Hunters who want to sort and select bucks based upon ages older than 3½ have the right to still perform so, but much more time spent studying each buck may be required. In enhancement to viewing in the field, use trail-camera photos and also home-video footage to refine her estimates. Also, when a buck has actually been harvested, examine your own ar estimates versus age estimates based upon toothwear and/or cementum annuli periods from a reliable lab. This will help you hone your an abilities at aging the deer in your an ar or habitat type.

4½ years

Because their stomachs, chests and necks are now fully developed, most four-year-olds have actually legs that show up too short for their body. They have actually fully-muscled shoulders, heavy swelling in your neck throughout the rut, and their waist has actually dropped down to come to be even with their chest. Offered adequate nutrition they’ll come to be structurally mature and can with 75 come 90 percent of their antler expansion potential. They likewise have a the majority of tarsal staining and also during the rut the stain might extend below the tarsal gland. Four-year-olds have actually an entirely different appearance 보다 one- come three-year-old bucks.

5½ come 7½ years

Other than in pick places, couple of free-ranging bucks exceed 5 years of period so I’ll combine five- come seven-year-olds. Bucks in this classification have foot that appear too short for your body. They likewise have number of other characteristics of 4 year olds including fully-muscled shoulders, hefty swelling in your neck during the rut, and also a belt that’s even with your chest. However, they likewise may have a pot belly and also a sagging back. Their raised body mass gives them a more rounded appearance, and they may look choose a tiny cow. They will certainly have accomplished 90 to 100% of your antler expansion potential, and they deserve to have highly stained tarsal glands throughout the rut, v the stain expanding well below the tarsal gland.

8½ and also older

A few free-ranging bucks do it come the post-mature age category. These bucks have actually passed their prime and regress in both body and antler size. They generally have loosened skin on your face, neck and also shoulders – normally visible together a “chin flap” – and also they may have actually pointed shoulder and hip bones. Your antlers can show age-related abnormalities such as abnormal points or wavy or curvy tines, and also they have actually an in its entirety “weathered” appearance.

As you examine age-specific body features you’ll notice there no age-specific antler attributes (other 보다 the selection of antler potential that might be reached at each age class, and also this percentage can’t it is in accurately estimated by viewing the antlers). Therefore, I indicate you don’t rely solely on antler size when aging bucks. Big antlers ~ above a younger deer and tiny antlers on an older deer can negatively influence your estimated age. I like to estimate age based specifically on body features with respect to location and time of year and then use antler size to “check” my calculation or to rest a tie if i can’t decide in between two ages.

For more assistance, ns recommend the book Observing and examining Whitetails by Dave Richards and also Al Brothers, as well as the pocket field guide to aging bucks created as a companion come this book. Also, QDMA has developed an educational poster, Estimating Buck Age, that provides photos that live bucks of known ages to highlight variations in body attributes by age class. Again, this provides a an excellent visual aid for educating hunters. Every one of these items are easily accessible in The Shed, QDMA’s online store.
