Specifically, horses are always on the lookout. Their long necks, widely spaced eyes, and mobile ears help them be aware of things all around them. Equine ears swivel in all directions, allowing them to hear and locate faraway sounds. These abilities are crucial to horses' survival, because despite their speed, they are not as fast as many of their natural predators. Early detection is therefore essential.
Binocular vision is essential to accurately judge distance and depth.
In terms of the horse's survival, it really doesn't matter - all he has to do is run the other way. Equine Body Language Take some time to observe horses from a distance, and learn a bit of their body language. If you can recognize these signs, you will be better able to predict and avoid danger. First, a horse will usually freeze. This makes him less noticeable to the potential predator, while allowing him to better identify the source.
