Most human beings are awake during the day and asleep at night. Owls live opposite to this diurnal way of life. This means that they sleep all day and remain active at night. As a result of this nocturnal living pattern, owls must also eat at night. Finding food in the dark, however, tends to be difficult. Certain aspects of their bodies have been specially adapted to facilitate this difficult task.
Owls have very large eyes, which absorb more light than normal. Since there is little light during the night, it is helpful to be able to absorb more of it. This helps owls to see in the dark.
Owls also have very good hearing. Even when they are in trees, owls can hear small animals moving in the grass below. This helps owls catch their prey even when it is very dark. Like owls, mice are also nocturnal animals. Mice have an excellent sense of smell which helps them to find food in the dark.
Being nocturnal helps mice to hide from the many different animals that want to eat them. Most of the mouse's predators: birds, snakes and lizards sleep at night, except, of course, owls.
