Not Sure What Your Horse Thinks? Watch His Ears

If you want to get an idea of what horses are thinking, just watch their ears.

The London Daily Mail reports that a study has found that horses, like people, can read each other's faces.

But they also get important information by paying attention to each other's ears.

For example, when a horse is curious or interested in something, it pricks its ears forward. When it's relaxed, its ears relax downward, and ears pinned back signal anger. 

"Although horses have very mobile ears, they can only swivel them round, point them forward, pull them up or flatten them back," the report quoted researcher and PhD student Jennifer Walthan.

A horse's ears are so important that if they're covered up, they can have a hard time figuring out what the other one is thinking.
