Nocturnal animals have developed over the years with many useful traits to help them live and be active in the dark. This move to nighttime living and hunting allowed animals to avoid certain predators …and hunt with less competition. Initially, most animals were diurnal, but adaptations that allowed some animals to become nocturnal are why many – especially mammals – evolved successfully. Other common diurnal creatures include many mammals, birds, and reptiles.īeing busy during both day and night is the most common animal activity group. This is what we have more commonly known as a ‘body clock’ which controls behavior rhythms such as:Īs I mentioned earlier, most primates are diurnal (which includes humans). Circadian timing systemĪlong with their nocturnal cousins, diurnal animals share a common circadian timing system. It’s interesting to understand that some diurnal animals aren’t able to distinguish anything at all. So although animals who have adapted to living in the dark hours of nighttime can distinguish the difference between colors and contrasts of the nocturnal world, diurnal animals have limited ability. The level of light intensity can be orders of magnitude dimmer at night. Diurnal animals function less easily at night That means that it has to be awake and active during the day.īald eagles and hawks are also awake with sunrise as this is when their prey is active, such as squirrels, and chipmunks. So it will need to acclimatize to the temperature around it – but also to warm itself, it needs to bask in the sun. For instance, a turtle may be diurnal because it is cold-blooded. Diurnalĭiurnal creatures wake and sleep with the rising and the setting of the sun. So let’s explore deeper by looking at creatures that are ready to start their day when the sun comes up. And often fragrances from night bloomers can be heightened. They even have white flowers that help them to be found at night. Many flowers will open during the morning in order to attract bees that are more active during the earlier part of the day.Īlternatively, some flowers, like the moonflower, open during the evening until after sunrise in order to attract nighttime pollinators. For example, plants follow rules evolved by their diurnal and nocturnal pollinators. The whole ecosystem is designed in intricate measure around these kinds of concepts. Humidity The ecosystem makes use of symbiotic activity times.Animals activity depends on many factorsĪn animal’s wakeful times can depend on many factors. This is more important when it comes to the challenge for food and hunting grounds. The lighter, warmer, and dryer environment of daytime suits many creatures, including most of the primate kingdom.īy sharing the load day and night, animals can max out their environment and occupy the same territory without the need for competition for space. Others, roughly 70%, have evolved to live and hunt in the darker, cooler, and more humid nighttime. The unique roles of each animal have evolved to ensure that they can utilize and optimize their environment and the world around them.įor this reason, some creatures take advantage of daylight hours. In general, evolution in the animal kingdom has taken place which fully takes advantage of all opportunities. Why animals are active at different times, days and seasons. Here’s an infographic that outlines the approximate periods of the day and night when these periods occur. Let’s start by exploring more about why animals – similar to their shift-working humans – often have different active periods during 24 hours. Read on, or watch the video below from the Ranger Planet Youtube Channel. We’ll explore these a little more shortly. Cathemeral (or Metaturnal) animals’ activity varies based on behavior and other factors.Īnimals vary in their active hours due to many factors. Crepuscular refers to animals active around dusk (Vespertine), and/or dawn (Matutinal). Diurnal animals are active during daylight hours. Let’s discover more about when animals are active in my helpful post, giving you all you need to know about when the animal kingdom gets busy! Here’s a quick roundup to start us off…Īround 70% of animals are active at night – Nocturnal. Some are busy working during the day, whilst others, a night shift.īut what about our furry friends from the Animal Kingdom? Are some animals only active during the daytime? And which animals get on with their lives during the hours of darkness and even before the sun rises? So when are animals active? Humans can be active at all hours of the day and night.
