Sorry, had to delete the answer in front of mine. I have been around horses for 12 years. I would know. When they are slanted backwards, he is paying attention to you, and is relaxed. When pinned back, flat against the head it is VERY mad, BACK OFF. When perked forward, it sees something, or is in a high strung mood. When you first approach a friendly horse, no doubtingly it will have its ears forward.
