Why owl eyes are so special?
The owl is the bird with the best eyesight in the world, which sleeps during the day and hunts at night. Their eyes are unlike other birds, located perfectly at the front of their heads. The eyes are large, round and designed to see in dim light.
Owls’ eyes are more like tubes than eyeballs. Owl’s eyes are fixed in orbits through bony structures known as sclerotic rings. Due to these rings, owls are unable to move their eyes.
They have binocular vision and can see an object with both eyes at the same time.
They are also famous for their outstanding neck mobility as their neck can move at an angle of 270° that’s why they can see at a large angle. They have 14 bones in their neck unlike humans with 7 bones only. When the neck is bent, the blood is not blocked from reaching the brain, whereas if the neck of a person is bent so much, then death will occur due to the blood being blocked.
An owl flies without making any sound
The owls are also amazing. It is the quietest breeding bird in the world. The edges of its wings are saw-shaped which helps it to fly silently according to scientific principles. The reason for this silent flight is that they keep listening to the voice of their prey till the end.
The owl’s flat, the half-apple-like face is also surprising. It helps to capture the sound waves and direct them towards their ears.
An owl has special ears

Species of an owl
Owls are divided into two main types.
1. Round-faced i.e. Strigidae
2. Heart-faced i.e. Tytonidae while in total there are more than 220 species. They are present in every continent of the world except Antarctica, 19 species have been discovered in Pakistan so far.
