The kiwi is a family of nocturnal birds endemic to New Zealand.. While it is difficult to say which came first, nocturnality or diurnality, a hypothesis in evolutionary biology, the nocturnal bottleneck theory, postulates that in the Mesozoic, many ancestors of modern-day mammals evolved nocturnal characteristics in order to avoid contact with the numerous diurnal predators.

Some crepuscular animals may also be active by moonlight or during an overcast day. Matutinal animals are active only after dawn, and vespertine only before dusk. A number of factors affect the time of day an animal is active. Predators hunt when their prey is available, and prey try to avoid the times when their principal predators are at large.

Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals.

Several types of owls are crepuscular—active during the twilight hours of dawn and dusk; one example is the pygmy owl (Glaucidium). A few owls are active during the day, also; examples are the burrowing owl (Speotyto cunicularia) and the short-eared owl (Asio flammeus). Much of the owls' hunting strategy depends on stealth and surprise.
Unlike most owls, burrowing owls are often active during the day, although they tend to avoid the heat of midday. But, similar to many other species of owls, they are mostly crepuscular hunters, as they can utilize their night vision and attuned hearing to maximum potential during sunrise and sunset .
