päevakajalised
Päevakajalised, also known as diurnal animals, are organisms that are active during the day and rest or are less active during the night. This behavior is a common adaptation to the environment and is often associated with the availability of food and light. Diurnal animals have evolved various strategies to cope with the challenges of daytime activity, such as avoiding predators and conserving energy during the cooler night hours. Examples of diurnal animals include humans, birds, and many insects. The opposite of diurnal animals are nocturnal animals, which are active at night. The term "päevakajalised" is derived from the Estonian language, where "päev" means day and "ajalised" means related to or characteristic of.
