melanistic deer | Buck Manager

Fawns are Twins, But Not Identical

Most people, including me, find any variation in white-tailed deer quite intriguing. In fact, most hunters and deer managers even select for certain characteristics, specifically when in comes to antler configuration. Depending on the individual hunter, they may look to harvest bucks with really wide antler spreads, bucks with numerous points, bucks with non-typical antlers, or very old deer. Color is also selected for by hunters because if the opportunity presents itself, many hunters will not hesitate to harvest a uniquely-colored deer. However, I do not know of any individual or ranch that manages for deer color.

Although there is some amount of color variation between all living whitetail, we all know what a white-tailed deer should look like. They are usually some variation of brown on top with white under the body, on the throat-patch, around the eyes and nose, and let’s not forget the white under the tail. After all, they are white-tailed. We know how a deer should look, but this is exactly why any color variation, even minor, sticks out. We, as predators, pick up on any abnormality or weakness exhibited by deer. This is why we do not see many white albino deer or black melanistic deer–they occur rarely, and when they do, these deer are removed from the population by hunters or natural predators. That is unless these deer are found in protected areas, such as urban or suburban areas.

Such is the case with the city of Austin, Texas. Melanistic deer naturally occur in this area and show up again year after year. Black-colored deer occur throughout the United States in very small numbers, but apparently the gene pool for melanistic deer is well-stocked in Austin. From a genetic standpoint, this makes sense. The “normal” color observed in deer is the result of dominant genes. Any variation in that color is caused by abnormal, or recessive genes. Just as many deer management programs spare certain bucks to concentrate genes for specific traits, the melanistic deer in Austin, Texas, have been spared because they live in a developed area.

This has allowed the very recessive genes for black hair, at least in white-tailed deer, to be passed on in a “protected” area with little to no predators. And although these genes are concentrated, the genes are recessive and do exist in an open population. So not every deer is melanistic, but melanistic deer can occur when melanistic deer, or deer that carry melanstic genes (but look normal), breed. The take home message as it relates to deer management on your property is that certain genes–even rare ones–can be increased within a population if managed and protected.

More Black Deer Spotted in Texas

While “black” deer, more accurately referred to as melanistic deer, are very rare across North America, it seems they are being spotted more frequently in central Texas. A few weeks ago I posted some photos of a melanistic buck in Austin, Texas, but it seems that animal is not the only white-tailed deer in the area with a color abnormality. Just check out the photos of these twin white-tailed deer fawns that were taken in the Northwest Hills area of Austin.

Dr. John Baccus, director of the wildlife ecology program at Texas State University, has been studying melanistic deer for over 13 years now. And as it turns out, Texas is a good place to study the dark colored deer. That’s because there just happens to be more black deer in eight Texas counties than in the rest of the world combined!

Black Deer are Really Rare

And as staggering as that statistic may be, most Texans still haven’t seen one! There may be more abnormally dark white-tailed deer in the central part of Texas than everywhere else combined, but don’t go there expecting to see one.

Dr. Baccus had this to say about Texas’ melanistic deer:

“Even though we have more melanistic deer here than in the whole world, they’re still extremely rare. It’s the rarest of the white-tailed deer, even rarer than the big-antlered deer. I get the harvest records every year from the Texas Parks and Wildlife Department, and generally, there are fewer than five of these melanistic deer that are harvested in any given year.”

Melanistic Buck Spotted in Austin, Texas

When it comes to white-tailed deer, we all know how they are supposed to look. Most are brown and white. But occasionally in nature we get genetic abnormalities and end up with something that looks totally different — which is usually white (albino) or even more rare, black. All mammals, including white-tailed deer, can have black fur and these animals are referred to as melanistic.

They are called melanistic because their body produces too much melanin, a dark pigment that causes their hair to be very dark brown or black. This variation is obvious to even a casual observer, but I’m not sureit impacts the deer itself or if the difference is even noticed by other animals in the herd.

Melanistic whitetails are the most rare color abnormality that deer can have — even more rare than piebald or albino deer. The photos seen here were sent to me and they allegedly came from somewhere around Austin, Texas. The photos are that of a melanistic white-tailed buck. The pictures where taken in a residential area so this rare buck may have lucked out.
