Use their ears, eyes and nostrils to express their mood.  They also communicate their feelings through facial expressions. 

It is extremely unlikely to see all horses in a herd lying down simultaneously.  This is because at least one horse will stand as a look-out in order to be able to alert the others of any potential dangers. 

Horses have near 360 degree vision.  They do however have blind spots directly in front and behind them. 

Horses use a range of different vocalizations to communicate.  Whinnying and neighing sounds are elicited when horses meet or leave each other.  Stallions (adult male horses) perform loud roars as mating calls, and all horses will use snorts to alert others of potential danger.  Mares (adult female horses) use deep smooth sounds, nickering, when they are nursing a foal (infant horse). 

Horses are undeniably clever animals.  Beyond being proficient at relatively simple learning tasks, they are also recognized as having the capacity to solve advanced cognitive challenges involving categorization learning and a degree of concept formation. 

Horses and other equines have better senses of smell and hearing than humans.  Their ears can turn in different directions to aid their hearing. 

 When horses look like they’re laughing, they’re actually engaging in a special nose-enhancing technique known as, “Flehmen,” to determine whether a smell is good or bad. 

 That's right!  Horses can't burp, at least not the way humans do.  They can't vomit or breathe through their mouths like humans do either.  A horse's digestive system is a one-way street, unlike cattle and other ruminants who regurgitate food to re-chew it.  Although they have a pretty efficient way of processing the tough fibrous foods that make up their forage, this long, one-directional system can cause problems that result in colic.

Wild horses generally gather in groups of 3 to 20 animals.  A stallion (mature male) leads the group, which consists of mares (females) and young foals.  When young males become colts, at around two years of age, the stallion drives them away.  The colts then roam with other young males until they can gather their own band of females.

 Horses with typical anatomy are, "Obligate nasal breathers" which means they must breathe through their nostrils and cannot breathe through their mouths.
