Horse facial expressions communicate information

25 Oct

An interesting PLOS paper describing The Equine Facial Action Coding System.

From the paper:

Horses are predominantly visual animals, with reasonable visual acuity that, at 23 cycles per degree, is better than domestic cats and dogs. While horses’ use of head and body posture in signaling has been described in observational literature, surprisingly their use of facial expressions has been largely overlooked. This is despite attempts to quantify facial expressions in horses’ close relatives, plains zebra (Equus quagga), and reports that horses do routinely use some apparently complex facial expressions (e.g. snapping and the estrous face, which both involve pulling back the lips and flattening of the ears)
