Matutinal

Natural world activity in early morning

Matutinal, matinal, and matutine are terms used in the life sciences to indicate something of, relating to, or occurring in the early morning. The term may describe the morning activities of crepuscular animals that are significantly active during the predawn or early hours and which may or may not then be active again at dusk, in which case the animal is also said to be vespertinal/vespertine. During the morning twilight period and shortly thereafter, these animals partake in important tasks, such as scanning for mates, mating, and foraging.
