Do great horned owls have good eyesight?

Why do owls have good eyesight?

Owls have good night vision for a few reasons. First, they have a lot more rods and not as many cones, so they lose color vision, but see a lot better at night. Also their eyes are very large, so they pick up a lot of light rays. Owls have a sort of mirror at the back of their eye called the tapetum lucidum.

Why do great horned owls have big eyes?

An owl’s eyes are large in order to improve their efficiency, especially under low light conditions. In fact, the eyes are so well developed, that they are not eye balls as such, but elongated tubes. They are held in place by bony structures in the skull called Sclerotic rings.

How does the structure of a great horned owl’s eye make it good for its function?

The size as well as the position of the eye is perfect for hunting at night. The bigger lens means that the owl can absorb as much light as possible. That is how the bird manages to see things even in low-light conditions. Consequently it provides an excellent binocular field of view.
