Are white tailed deer nocturnal or diurnal?

Deer are cathemeral, meaning that their activity patterns can vary depending on factors such as the time of day, season, and location. While white-tailed deer are typically more active in the morning and evening hours, they may also be active at night, especially during the summer months when the weather is warmer and food is more abundant. Some white-tailed deer populations have been known to exhibit nocturnal activity patterns, meaning they are most active at night.
