A new study has found that horses use a whistling technique to produce their signature whinny sound. The research, conducted by scientists at the University of Wisconsin-Madison, provides fresh insights into the complex vocal mechanics of these animals.

Why it matters

Understanding how horses create their distinctive vocalizations can offer valuable clues about their communication, social behaviors, and overall biology. This knowledge could have implications for horse training, welfare, and even conservation efforts.

The details

The study, published in the journal Equine Veterinary Science, analyzed high-speed video and audio recordings of horses as they whinnied. The researchers discovered that horses generate the whinny sound by rapidly expelling air through a small opening in their vocal cords, creating a whistling effect.
