Deer, graceful and amazingly shy animals, are often spotted in many areas and parts of the globe. One of the fascinating deer behaviors is their activity cycles which can be day and night or twilight for some species.

Knowing what deer do during the day can be very important for those who are trying to watch or hunt them.

In this article, we will look into the issue of whether deer are nocturnal, diurnal or crepuscular, determinants of their activity schedules, interesting facts about nocturnal deer and how to hunt these evasive creatures. Participate with us in unveiling a deer secret world.

Are Deer Nocturnal Animals?

Deer are considered to be nocturnal animals and thus most active during the two twilight hours of dawn and dusk. Rather than nocturnal, it is more accurate to say deer are crepuscular, meaning they are most active during the twilight hours.

This behavior helps them to keep them away from predators as well as they have enough light to search for food.

Although some deer might be active at nighttime in places with minimal human presence, they are considered mainly crepuscular animals.

These actions are thought to be the most common strategy of deer survival as they take advantage of both day and night for feeding and moving. However, not all deer are strictly nocturnal, because they are more active during the twilight hours.

Why Are Deer Nocturnal?

A deer is a nocturnal creature that is mostly active at night. Several factors contribute to this behavior.

1. Predators

Amongst the key reasons why deer are nocturnal is to escape predators. Most of their enemies, like coyotes, wolves, or mountain lions, are more active during the daylight hours. The nighttime activities of deer not only diminish the chance of being hunted but also increase their chances of reproducing.

2. Temperature

The Temperature difference between night and day is an important factor that contributes to the thermal cycle in many areas. Deer do not have a winter coat, and so can overheat quickly, so they might prefer to be more active at night when it's cooler.

3. Food availability

Grasses and herbs constitute an essential part of deer's diet. In some places, deer may have plants in abundant or easy-to-access areas at night, therefore deer tend to feed during these times.

4. Human activity

The threat of encounters or activities near humans can make the deer so sensitive. By being active at night when humans are less likely to be around, deer can avoid potential disturbances.

Fun Facts About Nocturnal Deer

1. Where do deer go during the day?

During the day, deer usually make their homes in dense vegetation such as forests or thickets, where they can take a nap and avoid dangers. They may also bed down in long grass or shrubs, allowing them to merge and stay undetected.

2. Are deer nocturnal in all seasons?

The deer are more active at night during all seasons, but the pattern of their activity may fluctuate, depending on food supplies, weather conditions, and predator activity. In general, deer often move about during the early dawn and late evening times.

3. How far can deer see at night?

Deer have good night vision and can see relatively well in low-light conditions. They possess a specialized layer called the tapetum lucidum located behind their retina. This unique feature amplifies their vision in low-light conditions by reflecting light across the retina. They can see objects clearly at night up to about 200 yards away.

4. How good is deer vision at night?

Deer have very sensitive night vision and can see even in dark places without many light sources. Again, deer have a reflective layer behind the retina called the tapetum lucidum, which gives them a supernatural ability to see at night by reflecting the additional light through the retina.

5. What color can deer not see?

Deer eyes are very sensitive to blue-green light wavelengths. According to research, deer can see blues up to 20 times better than humans can. Therefore, their night vision may be poor when it comes to distinguishing between these colors. But they can still differentiate colors including red and orange which are not so prominent to them.

6. How far can deer smell hunters?

Deer are equipped with a very good sense of smell, and they can sense scents from long distances. They possess up to 297 million olfactory receptors in their noses, in contrast to about 5-6 million in humans, which lets them detect even the faintest odors. They can sense hunters that are located several hundred yards away, depending on the weather, wind direction and other factors.

How To Hunt Deer That Are Nocturnal?

Deer that are most active at night are quite challenging to hunt, but you can always employ some tactics to improve your chances. Here are some key tips for deer hunting that you can keep in mind:

1. Learn Habits

If you want to have a good hunt, you should be able to foresee the deer's behavior and habits when it is dark. Investigate their preferred feeding habitats, go-to resting places, as well as places they get to and from these sites.

2. Set up Trail Cameras

Trail cameras have the potential to give us a lot of information about the nocturnal deer’s habits. Try positioning your cameras near food sources or routes of travel and you will be able to receive vital data to help in hunting plans.

3. Hunt During the Rut

Along with the deer rutting season, the nocturnal activity becomes a more common feature even during the night. It is likely that by hunting in the dawn and dusk hours, you can see nocturnal deer during the daylight.

4. Use Scent Control

Deer possess a sharp sense of smell, thus employing scent management strategies is crucial to the successful hunt of nocturnal deer. It is suggested to use scent blockers while you are in the field.

For your hunting clothes, use a scent-free detergent, don't use fragrant products. Also, rubber hunting boots are better than leather hunting boots in controlling scent.

5. Hunt Near Bedding Areas

Placing your trail camera in the vicinity of a bedding area for the deer during the daytime can help increase your likelihood of observing them while they are leaving these areas to feed at night.

6. Utilize Calls and Decoys

With the help of whistles and decoys, nocturnal deer can be attracted to your location. Try different calls and decoy setups, and experiment until you find the combination that works for you and your hunting area.

7. Utilize Moon Phases

Some may believe that deer activity will be influenced by moon phases. During a full moon, deer may be more active at night due to increased visibility. Pay attention to moon phases and plan your hunting trips accordingly.

8. Stay Concealed and Quiet

When hunting nocturnal deer, it's essential to stay concealed and avoid making noise. Use camouflage clothing, and scent control products, and remain as quiet as possible to prevent spooking the deer.


In summary, deer are mainly crepuscular mammals and they are most active at the dawn and dusk hours. The nocturnal behavior of animals is regulated by various factors including predator avoidance, temperature, food availability, and human activity.

Recognizing these factors can assist hunters and nature lovers in better understanding the complex behaviors of these nimble animals. Having the right skill and ability, observing or hunting the deer at night can be a peak of excitement.
