Diurnal animals are those that are primarily active during daylight hours. They are adapted to be active, hunt, forage, and perform various activities during the daytime. Examples of diurnal animals include many bird species, such as eagles, sparrows, and robins, as well as certain mammals like squirrels, monkeys, and some species of deer.
Cresporal, auroral, and vesporal are not recognized terms for categorizing animals based on their activity patterns.
The animals that are active during the daytime are called diurnal.
Diurnal animals are those that are primarily active during daylight hours and rest or sleep at night.
Examples of diurnal animals include humans, birds, most primates, many species of insects, and some reptiles.
In contrast, nocturnal animals are active at night, such as bats and owls, while crepuscular animals are most active during dawn and dusk, like deer.
Being diurnal or nocturnal often depends on factors such as temperature, predator-prey relationships, and the availability of food.
