Owls are able to hunt in the dark primarily due to their exceptional night vision and acute hearing. Their large eyes are adapted to gather as much light as possible in low-light conditions, allowing them to see in the dark. Additionally, their specialized feathers enable silent flight, helping them sneak up on their prey without being heard. Lastly, owls have asymmetrical ear placements on their heads, which allows them to pinpoint the exact location of sounds, aiding in their hunting abilities in the dark.
