Species

Horse

A prey species whose most informative channels are postural and facial rather than vocal, and where separation is the dominant driver of calling.

Capture note

Whinnies carry two independent fundamental frequencies at once; analysing only the stronger one discards the arousal information carried by the weaker.

Signature signals

What an experienced observer looks for in this species.

Whinny
audio
Long-distance contact call, typically separation-driven.
Pinned ears
video
Ears flat against the neck — a clear distance-increasing signal.
Weight-shifting and pawing
video
Frustration, anticipation or discomfort depending on context.

Limitations

• Ear position is the strongest visible channel and is frequently out of frame in handheld video.
• Pain signals in horses are subtle and easily confused with normal resting posture.
