Crepuscular
Crepuscular refers to animals that are primarily active during twilight, that is during dawn and dusk. The term is derived from the Latin word "crepusculum", meaning "twilight". Crepuscular animals are distinct from diurnal and nocturnal species, as well as those that are matutinal (active in the morning) or vespertine (active in the evening).
Characteristics[edit | edit source]
Crepuscular animals take advantage of the cooler parts of the day, which reduces the risk of predation. Many predators are either diurnal or nocturnal, making crepuscular times safer for certain animals. Some crepuscular animals may also become active on a bright moonlit night or on a dull day. Some animals selectively feed on certain prey at twilight, depending on the different levels of light.
Examples[edit | edit source]
Examples of crepuscular animals include many species of birds, insects, and some mammals like deer, rabbits, and housecats. Certain primates and big cats like jaguars and tigers are also considered crepuscular.
