Was just telling Horsie about a program I listened to on NPR, which related to horses, and their whinnies. They theorised that the high sound isn’t coming from the vocal cords, but from just above the larynx, being similar to a whistle (in human terms) instead. Horsie told me they don’t use it to communicate anymore because for that they have “Horsemobile”, a portmanteau, so to speak, similar to “T-Mobile”. 🤣
