Horses Think How the animal works  ·  not what to do about it

The eye is where this starts

A horse sees almost all the way around itself, and cannot see its own nose.

Eyes set on the sides of the head give a horse close to a full circle of vision with only a narrow binocular strip in front. It is a prey animal's arrangement: enormous coverage, poor depth except straight ahead, and it explains a great deal of behaviour that gets read as temperament.

Set the eyes on the sides of the head and you get a field that runs nearly all the way round, a narrow strip of overlap in front, and two places the animal cannot see at all. Much of what gets read as temperament begins in that geometry.

Plan view · the field as it is described
Plan view of the equine visual field: a binocular strip forward, monocular fields to each side, blind wedges at the nose and directly behind BINOCULAR 60–70° the only strip with depth BLIND AT THE NOSE BLIND DIRECTLY BEHIND MONOCULAR left field, no depth MONOCULAR right field, no depth

Two blind spots, and one of them sits where a person usually stands

Coverage of roughly 350 degrees leaves very little unseen, but the unseen is awkwardly placed: a narrow wedge directly behind the hindquarters, and a wedge below and in front of the muzzle. An object brought slowly toward the nose passes out of view before it arrives, which is why a horse tips and turns its head to inspect something close.

Outside the binocular strip each eye works alone. That monocular image carries movement, shape and contrast, and almost no depth — so a thing moving at the edge of the field registers as something moving with no distance attached to it.

Section 07 · Contested ground

The most repeated account of how horses live together is also the least settled.

Linear hierarchies are easy to draw and hard to find. Observations of free-ranging bands describe family groups, movement initiated by different individuals on different days, and relationships better described by who tolerates whose company than by rank. This section is here because the question is contested, not because the story is wrong.

Three to read first

Ears

Independently mobile and pointed at whatever has attention, which makes them the most readable signal on the animal.

Signals

Startle

A reflex, not a decision — it happens faster than any deliberate response could.

Response Time

Light and dark

Excellent in low light, slow to adapt between the two — a dark doorway at noon is a genuine problem.

The Eye

Every entry separates what is observed from what is inferred, and says where the science is contested. Nothing here is guidance: this site describes how the animal perceives, learns and lives with others, and does not say what to do with one.
