This? This is cool. Hang on while I turn into a giant horse nerd for a minute here.
Horses will not lie down unless they feel totally at ease and unthreatened, and especially in the flat-out position. They only lie flat like the two in the front if they’re going to do some REM sleep, which only lasts about 45 minutes. Normally a horse will lie in sternal recumbency, like the two in the back.
The fact that these ponies feel comfy enough to lie down and nap on a beach full of people is impressive— it means they live a life generally free from stress and have learned that they can trust humans. I’d love to know which group of wild ponies this is!
Fun fact: in a herd of horses taking a nap, there will always be at least one who is standing, although they may be relaxed (see cocked leg on rightmost horse). This horse has the job of being the lookout.
horses also lay down when they die or are killed. this is a beach funeral please have some respect.
