Owls have adaptations that allow them to detect predators, including humans, in the dark. These adaptations include the ability to:
Night vision – large eyes allow the owl to see better at night in dim light
Silent flight – owls have soft feathers that help them avoid making a sound which might help predators locate them
Powerful vision – allows owls to see small moving objects from great distances in very little light due to a dense concentration of light sensitive cells
Great hearing – enables predators to detect even minuscule noises
Sharp eyes – eyes located at the front of their head and pointed inwards gives owls binocular vision to see more detail
