Deer antlers – a sometimes impressive sight!

After living in apartments for many decades, it was a thrill for me when I was able to live in a house surrounded by a yard on all sides. It was even cooler when I discovered my neighborhood was home to a variety of birds and animals, undoubtedly helped by the fact that there are woods, a creek and a pond nearby. One of my greatest delights has been the white-tailed deer (Odocoileus virginianus), that visit – even though some neighbors loathe them and chase them from their yards. I’ve found that a home-made deer repellant, as well as a store-bought one, work well to keep these visitors from eating the plants I want to keep. The veggies are in a narrow, fenced garden that they cannot enter so no problems there either.

While does and fawns are the main passersby, a variety of male deer visit, too. Some have been the offspring of local does, while others have come in during mating season.The buck above was kind enough to drop one antler in my yard and I found the other in the woods. Learning about their antlers has been interesting and showing the antlers to kids that I have mentored and visitors is fun, too.  So what process leads to these impressive growths?

Male fawns that are 6-9 months old during their first winter (fawns are born in the spring) are called “button bucks” because they have nobs on their heads that are covered with skin. In their second year, their antlers become longer but are still rather short.

The males grow new antlers every year; they are the fastest growing bone in mammals. They start growing in late spring and are at first covered with a fuzzy skin, called velvet, which provides nutrients and oxygen to the growing bone. The velvet has blood vessels and when the deer rub it off, for example, against tree branches, you can see traces of blood. When the velvet has been shed, the antler becomes dead bone and it doesn’t hurt when the antler is shed.

The way that the antlers grow is influenced by the deer’s nutrition, age and genetic background. Some have simple spikes, which may become branched antlers as the deer grows older. Some “racks” (the pair of antlers) will have many branches.

The bucks lose their antlers at the end of winter and you can find them on the ground if the squirrels don’t get to them first! I had left some antlers outdoors as garden decorations until one day I found a couple had been gnawed by the squirrels. The squirrels eat them to help wear down their front teeth (which are always growing) and to obtain minerals such as calcium.

As long as the does are around, the bucks will come, which makes me happy. They may not be as comfortable staying in the yard as this member of Schatje’s family, but their brief visits will remain a source of pleasure and learning!

Thanks to Kevin Hinkle for letting me photograph the skull.

    • Your yard seems more like a wildlife garden! My problem is to see the birds as they are so wild and to keep the wild boar out of the veg plot! Good luck and will return to see more of your blog. Like the idea of salt blocks, maybe the birds here need that??

      • My yard does indeed have a great variety of avian visitors, although some are sporadic. This morning there were suddenly about 40 red-winged blackbirds foraging under the feeders. The opossums and racoons come at night and though I know we have coyotes in the neighborhood, I haven’t seen any. Keeping a wild boar out of your vegetable plot seems like quite a challenge – you would need a strong fence that they couldn’t burrow under, right?
