White Rhinoceros

White rhinoceroses are diurnal during the winter and crepuscular during the summer, in order to avoid the hottest parts of the day.

White rhinoceroses are generally sedentary and do not migrate from one place to another during different seasons. Instead, they alternately feed and rest day and night. White rhinos are both diurnal and crepuscular, differing across seasons.

During winter, they are diurnal, meaning their peak hours of activity occur during daytime. On the other hand, white rhinoceroses are crepuscular during summer seasons, with peak hours of activity between 5:00 AM and 9:00 AM and 3:00 PM to 6:30 PM. This shift is a way to avoid hotter weather in the summer, when they are least active and spend most of their time wallowing in mud baths.
