Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night.

In zoology, a crepuscular animal is one that is active primarily during the twilight period, [1] being matutinal, vespertine/vespertinal, or both. This is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daytime and of night, respectively.

At night they often sleep at water, if there is a water source available, to flee quickly from predators if awakened. Small populations of Muscovy ducks can also be found in Ely, Cambridgeshire , Calstock, Cornwall , and Lincoln, Lincolnshire , U.K. Muscovy ducks have also been spotted in the Walsall Arboretum .
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.

The ducks splashing around in the pond was my favorite part! Commenters were all gushing over the Cheese and Quackers' cute video. @D's Useless Farm pointed out, "The snow on their beaks looking ...
