Usually this means that a horse is angry, and it is threatening another horse. When a horse is mad, the whites of its eyes may show, and the teeth will usually be showing. If a horse's ears are back, it can also mean that it is concentrating. If you watch horses that are running or competing, there ears are usually back. When a horse is really thinking, its ears go back..
ONE OR TWO EARS SLIGHTLY BACK:
this usually means the horse is listening to something behind it. If you are riding and the horse has one or more ears back, this usually means it is listening to you.
EARS FORWARD:
If the ears are tipped forward and stiff, and the horse shows the whites of its eyes or flares its nostrils, this means that it is scared or a interested in something. If the ears are just held forward and the horse shows no signs of fear, it just means the horse is listening.
TAIL SWISHING:
This is usually a warning to tell other horses or animals (or people!) to get out of the way. It is usually followed by a kick. This kind of swishing is usually done quickly side-to-side, and accompanied by ears back or little kicks. There is another kind of swishing, too. Horses do it to get insects, like flies, off of them.
BUCKING:
Bucking is usually a sign of joy. Horses will sometimes take off running and bucking. Their ears will be back, and sometimes they will grunt. Horses like to buck because it stretches their muscles, and it is fun! Sometimes bucking can also mean the horse is just being a brat or it is a bit scared.
REARING:
Horses usually rear when they are play fighting. It is commonly seen in foals playing with each other or their mother. Stallions will rear when they fight. Horses might rear out of fear, when there is no escape.
