Burung hantu tidak rabun di siang hari, matanya nampak separuh bukan kerana dia mengantuk atau tidur tetapi untuk menghalang cahaya yang banyak masuk ke mata kerana anak mata hitamnya tidak boleh mengecil seperti manusia, dia sedang mengawasi anda keadaan ketika anda sangka dia tidur.

National Geographic Wild

Tiger, Their night vision is around six times greater than humans’ is, but Allah created the excellent night vision is the owl, with 10 times the night vision capabilities as humans. The owl can twist it’s neck up to 270 degrees. Owls can see in the daytime. Their pupils don’t get as small as ours in bright light, so to block out the extra light, they often close their eyes half-way or more. They may look sleepy or even half asleep when really they are wide awake and alert.
