What does the term nocturnal describe about an animal's activity pattern?

• A. Active during the day
• B. Active during the night
• C. Active at dawn
• D. Active at dusk

Answer: (B)

Nocturnal describes animals that are active during the night. This pattern means they rest during daylight and move, forage, or hunt after dark. Understanding this helps in planning care and handling in rehab, since many nocturnal species are most active, and most sensitive to disturbance, at night. It also helps distinguish from diurnal creatures, which are active during the day, and crepuscular ones, which peak in activity at dawn and dusk. Examples of nocturnal animals include bats, owls, and many small mammals.
