East Friesian Sheep Vision

Sheep have poor depth perception (three dimensional vision) especially if they are moving with their head up. This is why they often stop to examine things more closely. Sheep have difficulty picking out small details, like an open space created by a partially opened gate. Sheep tend to avoid shadows and sharp contrasts between light and dark. They are generally reluctant to go where they can't see well.

For many years it was believed that sheep and other livestock couldn't perceive color. It has since been proven that livestock process colors necessary for color vision. Research has shown that livestock can differentiate colors though their color perception is less than 50% of a humans color perception.

Have a super weekend!
