Quick Answer
To determine the age of a caribou before taking a shot, observe the size and shape of its antlers, note the presence and coloration of horn tips, and consider its overall body condition and size. A cow caribou typically has a smaller rack and lighter body than a bull. The age of a caribou can also be estimated by the number of tines on its antlers.
Assessing Antler Size and Shape
When hunting caribou, the size and shape of an animal’s antlers can be a good indicator of its age. A bull caribou’s antlers will typically grow larger and more complex with each passing year. By age 5, a bull caribou’s antlers should have at least 4-6 tines on each beam, with the main beams being at least 3 feet long. If an animal’s antlers are smaller than this, it may be younger.
Evaluating Horn Tips and Body Condition
Another way to estimate the age of a caribou is to examine the coloration and presence of horn tips, which are the hardened, bony tips at the ends of a caribou’s antlers. In older caribou, these tips are often worn down and bleached white, giving the antlers a distinctive “brushed” appearance. Additionally, a well-conditioned caribou will have a well-muscled body and a relatively low body fat percentage, which can be an indication of its age and overall health.
Considering Seasonal Variations
It’s also essential to consider the time of year and seasonal variations when estimating the age of a caribou. For example, caribou that are migrating or in rut may appear more worn and weathered than those that are grazing in a stable habitat. By taking these factors into account, hunters can make more accurate estimates of a caribou’s age and make more informed decisions when taking a shot. In Alaska, for instance, caribou may be more active during the summer months, making it easier to assess their overall condition.
