* Elephant Poop is More "Spectacular": Elephant dung is simply larger and more visually striking. The sheer size and volume make it more interesting to film and watch.
* Elephant Poop is More "Educational": Elephant poop is often discussed in documentaries and educational content, focusing on its role in the ecosystem and its use for research. This creates a larger pool of videos on the subject.
* Horse Poop is More "Everyday": Horses are common domestic animals, and their poop is less unusual. It's not as captivating a subject for most viewers.
* Accessibility: Elephants often live in zoos or wildlife parks, making it easier to film their behavior. Horses, while common, are less likely to be observed in situations where filming their poop would be easy.
It's important to note that this is just a possible explanation. It's also possible that the perception of the difficulty in finding horse poop videos is just a quirk of personal experience, and there may be plenty of videos out there if you look hard enough!
