Rabbits are crepuscular, meaning they are active at dusk and dawn.
Crepuscular, diurnal and nocturnal are terms used to describe the time of day during which an animal is active. Many animals develop distinctive behavior patterns that are part of their general adaptation to the environments in which they live. Periods of activity tend to be easy for biologists to observe and are commonly used as tools to assess whether animals are stressed or frustrated, or pressured into unusual behavior. Knowledge about when an animal should be active can also be used as an indicator to suggest that an animal may be sick; owls, for example, are usually seen at night, which makes an owl a cause for concern if seen at noon.
Owls are a well-known nocturnal creature.
When an animal is considered twilight, it is active during the twilight, dawn and dusk hours. The word “twilight” is derived from a Latin word meaning “twilight”. Many animals take advantage of twilight to feed, fetch water, and engage in other behaviors because they know that predators are not as active at twilight. Visibility is also a challenge at dawn and dusk, making it easier for animals to hide from potential threats. Rabbits and cats are both twilight.
Deer are crepuscular, meaning daylight and nighttime can be particularly worrisome.
Nocturnal animals, on the other hand, only come out at night. Many of these animals have a specially developed sense of sight that helps them see in the dark, and they often also have excellent hearing. There are several reasons why an animal is nocturnal; many desert animals, for example, are active at night because it is colder and, as a result, their rate of water loss slows. Two famous nocturnal animals are bats and owls.

Animals that are active during the day are known as diurnal. Like crepuscular and nocturnal animals, the daily patterns of diurnal animals are established through circadian rhythms, patterns built into their body chemistry. Being active during the day certainly has some advantages, especially for animals with poor visibility like humans. Humans also tend to encourage diurnal behavior among the animals they interact with; dogs, for example, are naturally crepuscular but learn to become diurnal through human interactions.
Bats sleep during the day and wake up at night.
Disruption of an animal’s established biological rhythms can be harmful. Nocturnal animals, for example, tend to feel very disoriented when forced to exercise during the day, which can cause a feeling of stress and unhappiness that can have a negative impact on the animal’s health. Diurnal animals are not adapted to be active at night, which means they can be vulnerable to predation when they are outside after dark, while crepuscular animals like deer can feel very stressed when they are outside in the heat of the day. day or late at night, and this can cause them to behave strangely, such as running into traffic.
