Understanding Bucks
Male white-tailed deer, commonly called bucks, are among New Jersey’s most recognizable wildlife. From growing antlers each year to dramatic changes during the fall breeding season, bucks follow a fascinating annual cycle that influences much of the deer activity homeowners notice.
What Is A Buck?
A buck is a male white-tailed deer. Most bucks grow and shed a new set of antlers every year, making them unique among North American mammals.
Although bucks often spend much of the year in small bachelor groups or alone, their behavior changes dramatically as the breeding season approaches.
The Life Of A Buck
Spring
Antlers begin growing beneath a soft, nutrient-rich covering known as velvet.
Summer
Bucks focus on feeding and growing antlers while often remaining in bachelor groups.
Fall
The rut begins. Bucks become more active, establish dominance, create rubs and scrapes, and search for receptive does.
Winter
After the breeding season, bucks conserve energy, recover body weight, and eventually shed their antlers.
Why Bucks Rub Trees
Tree rubbing is one of the most noticeable signs of buck activity.
Bucks rub young trees to help remove velvet from their antlers, communicate with other bucks, and mark their territory during the breeding season.
For homeowners, buck rubbing can permanently damage or even kill young ornamental trees.
Understanding Antlers
Antlers are one of the most remarkable features of white-tailed deer.
Unlike horns, antlers are grown and shed every year.
Their size and shape depend on several factors, including:
- Age
- Nutrition
- Genetics
- Overall health
Growing antlers requires tremendous energy, making high-quality food especially important during spring and summer.
The Fall Rut
During autumn, increasing daylight changes trigger the rut, or breeding season.
Bucks become much more active, travel greater distances, compete with other males, and spend more time searching for receptive does.
Many homeowners notice increased deer movement—and more deer crossing roads—during this period.
Why Homeowners Should Understand Bucks
Learning about bucks helps explain many of the changes homeowners notice each fall.
Understanding buck behavior can help you:
- Protect young trees before rubbing begins.
- Anticipate increased deer movement during the rut.
- Recognize seasonal behavior changes.
- Better understand the wildlife visiting your property.
