This buck displayed an abnormal left antler throughout its life and was always seen walking with a limp. David Osborn, deer research coordinator at the University of Georgia, examined the deer after it was harvested at age 5 1/5 and found its right "elbow" joint had fused together after being shattered and the left side of its skull around the pedicle also showed signs of injury (the combination suggested the deer had been hit by a car). Both the leg injury and the skull injury likely contributed to the abnormal antler formation.

Lesions and bald spots indicate mange.

The coats of piebald deer are mottled with patches of white and patches of normal brown or gray. Piebald deer may also display other unique traits, such as short legs and an overall "dwarfish" appearance compared to normal deer, and abnormal curvature of the spine.

This buck took a beating. The damage included loss of the right eye and injury to the verges or muscles around the mouth, resulting in a dangling tongue. Based on experiences with captive deer, experts say that dangling tongues are most likely the result of an injury to the jaw or mouth rather than a disease issue. One doe with this problem, photographed over a period of months, was able to eat normally and appeared to remain healthy.

Like humans, deer can acquire many types of internal and external tumors, cysts, swellings, cancers, and defects. Causes vary from injuries to bacterial and viral infections. None are known to be a serious concern for populations and the outcome for each individual is never certain.
This buck was photographed feeding and moving about normally, in spite of its obvious problem. A wide range of potential causes could be involved from injury to infection.

Many hunters fear they see mange or some other strange disease in a photo when really the deer is just in a pelage transition. This is a normal transition from summer to winter coat.

This doe was photographed over a period of weeks, during which time the strange growth on its nose grew in size and then began to break up. Somehow the deer was still able to eat and breathe. Neither the cause of the growth, nor the doe's fate, are known.

A prominent overbite or underbite in deer is usually the result of a rare genetic anomaly that is present in most deer populations. It rarely affects the health of the individual and is not a population concern. Harvesting deer displaying a particular genetic trait will have no measurable impact on the trait's prevalence in a free-roaming population.

Both piebald and albino deer display genetic anomalies that occur rarely in all deer populations. True albino deer lack skin and hair pigments and are completely white. Their eyes are tinted pink.

Deer warts, or "cutaneous fibromas," are caused by a papilloma virus. They are usually temporary and can vary from half an inch to several inches across. The virus is uncommon and affects only a small percentage of deer, so it has little or no impact on deer populations. It is not transferable to humans. Most cases are minor, but in rare cases, dense fibromas may interfere with eyesight, breathing, feeding or mobility.

Hemorrhagic Disease is caused by a virus that is transmitted to deer in summer and early fall by biting insects. It is fatal to some deer, while others survive. Symptoms include high fever (and associated thirst), lameness, and cracked or sloughing hooves. In the photo on the right, notice the open sores on the buck's knees, which are associated with lameness. The deer has literally been walking on its knees. Since it was likely recovering. Sick and dead deer with HD are often found in or near water because of the high fever. If you locate sick or dying deer in any season, alert your state wildlife agency.
While it's likely this doe is, or was, pregnant, the amount of swelling appears excessive even for triplets and suggests complications.

Among the many potential parasites hosted by whitetails is the arterial worm, which lives in the carotid arteries of deer at one stage of its life cycle. the worm reduces blood flow and interferes with the function of the jaw muscles that control chewing and swallowing. As a result, food builds up in the cheek and becomes impacted. Death is possible in the most serious cases, but infection rates are not significant enough to be enough to be a population concern.

This bucks' facial swelling is thought to be related to infection, but the exact cause is not clear.

Some hunters blame "genetics" for weird antlers when in most cases injuries are the cause. A wide range of injuries can affect antler growth, from damage to the antler bases to the skull around the pedicle, or to the antlers while they are growing.

You'll find these and many more photos in the new book, "Deer Cameras: The Science of Scouting," published by the nonprofit Quality Deer Management Association (QDMA). The book was written by a team of whitetail experts and explains how to use trail-cameras to estimate deer density, buck age structure, herd health and more. It also helps you interpret buck movement patterns based on the latest science, and use photo evidence to more effectively hunt mature whitetail bucks. Deer Cameras: The Science of Scouting is available at www.QDMA.com or call (800) 209-3337.

Most of the time bucks get credit for being bruisers and duking it out with other deer, but does often go head to head as well. Like these two deer for example.
