Owls have silent flight due to the outer edges being frayed like a flag. Owls catch their food primarily at night but not all are exclusively nocturnal as you can see below. Because they have long flexible necks they can rotate their heads 260 degrees. Their large eyes face forward that allows this bird to have binocular vision enabling them to judge distances between objects and maneuver through thick cover.

Of course their sight is not as effective at night for any distance and they rely on their hearing to locate and pinpoint prey. Most owls have asymmetrical skulls, with ear openings at different levels. The right ear is positioned high on the head while the left ear is low.  This allows sound to reach one ear before the other which enables the owl to get an exact fix on sounds made by their prey. In experiments performed in totally dark rooms where eyesight is useless, owls have caught mice on a leaf littered floor with 100% accuracy.
