The owl is not an herbivore. Owls are carnivores and hunt their prey, which consists mainly of insects, amphibians, reptiles, rodents and other small mammals. Owls are capable of killing animals that are larger than them.
Most owl species are nocturnal and do their hunting during the night. However, there are some species that are active during the day and twilight. Owls fly very quietly and are able to surprise their prey. An owl uses its powerful talons and beak to capture and disable prey. The coloring of owls enables them to blend in with their environment to reduce visibility to predators.
