UPSC IAS – 2023
Only two of the listed fauna are generally nocturnal or most active after sunset.
1. **Lion-tailed Macaque:** These are diurnal animals, meaning they are primarily active during the day.
2. **Malabar Civet:** This species is known to be strictly nocturnal, active mainly during the night.
3. **Sambar Deer:** While they can be active during the day, Sambar deer are often crepuscular (most active during dawn and dusk) and their activity often extends into the night, especially in areas with human disturbance. Thus, they are frequently most active after sunset.
Therefore, the Malabar Civet is nocturnal, and the Sambar Deer is often crepuscular/nocturnal, fitting the description “generally nocturnal or most active after sunset”. The Lion-tailed Macaque is diurnal. This makes a total of two species out of the three listed.
