owls have good hearing to hear who is comming
All owls have incredibly tiny 'nostrails' on their beak, which allows them to smell and breathe, though their sense of smell isn't unlike ours. Not too strong, yet not weak.
Their large eyes, good hearing, speed and flight accuracy, and talons for catching things.
owls are good for their eye sight.
This is an adaptation.
owls have very, very good vision. they can see in almost no light. they also have an excellent sense of hearing, and most owls fly silently so that they can hear any sounds around them. they cannot, however, use echolocation like bats as portrayed in the "silverwing" books.
Owls catch their food using hearing, eyesight, silent flight and strong talons, gripping the prey in their feet.
They need hearing to help them catch their prey.
