Why Do Nocturnal Animals Come Out at Night?

As with most animal behavior, it comes down to survival. Whether it’s avoiding being eaten by another animal or being able to find food, nocturnal animals have plenty of good reasons to sleep during the day and hunt at night.

Temperature

Many reptiles sleep during the day to avoid the hot afternoon temperatures. For example, Copperhead snakes spend much of the daytime sleeping under logs and leaf litter. Then they forage for cicadas and small rodents at night.

Predators

Animals such as mice are nocturnal because many of their predators are out during the day. While there are also predators at night, these small animals have a better chance of going unnoticed as they forage for food and water. During the day they can rest safe and sound within their burrows and at night they can search for food.

Prey

Some animals also come out at night because their prey comes out at night. For example, owls hunt for mice at night, which also happen to be nocturnal. Catching prey at night can be more difficult, but nocturnal predators are equipped with adaptations like great hearing and eyesight.

Competition

Animals are nocturnal because there is too much competition during the day. For example, bobcats might hunt during the daylight so coyotes hunt at night. This allows each species the chance to hunt for food without constantly fighting each other.

The coyote picture shown above is from one of our night trail cameras at the Science Center which captures still photographs. Trail cameras are predominately used to watch and track wildlife. They are perfect to place in a remote location and see what wildlife is in the area. It is surprising what you will see and how much wildlife is around us at night.
