Which animal behavior describes greater activity during dusk and dawn?

The behavior described as greater activity during dusk and dawn is referred to as crepuscular. Animals that exhibit this behavior are primarily active during the twilight hours of dawn and dusk, which can help them avoid predators and take advantage of optimal hunting or foraging conditions when the light is neither too bright nor too dark.

In contrast, nocturnal animals are active during the night, while diurnal animals are active during the day. Vigilant behavior, while it can occur during any time of day, refers more to an alert state rather than a specific period of activity. Understanding these distinctions is important for wildlife management and control, as it impacts the timing of interaction with various species.
