Jakunen, if you make a sound that is a sort of cross between a hiss and a swish, then rats will immediately seek cover. It's the sound of a plummeting bird of prey.
Most rodents will, as will most small birds, and even ducks (haven't tried it on wild ducks though, only our domestic ones). I know the inherited instinct for these things is strong, we've hand-reared chickens, ducks, hamsters and gerbils and all of them display all of the normal instincts you see in their wild counterparts.
Anyway, I have (momentarily) felt true fear in a horse, and "agitated" (as used in the article) is most certainly not a word I would use to describe it... something more like "absolutely terrified" and "bolting for dear life" would be closer to it. And when that happened I was the most scared I've ever been whilst riding, because horses are strong animals, and the flight instinct is even more strong, and you just
know that you are a completely out of control, that you are an absolutely helpless passenger, and it's a very worrying experience.
So presumably to a horse, a boar is not classed as being as dangerous as a predator. Which is understandable, I've not heard of a pack of hungry boar bringing down a horse...
And whilst I will happily admit that I don't know much about how dogs react to things, I understand that when dogs start barking in woodland, it is usually because there's something like a squirrel or a hedgehog or a badger around. Horses will happily spook at those animals too...
OK, rant is really over this time.
Sorry for it being a rant rather than slightly more polite... but owing to riding on busy roads, you develop a mindset that everyone is a potentially dangerous idiot with absolutely no knowledge of horses, and that is the most sensible mindset to have... (minor example, when I was still in primary school, I was out riding on a quiet woodland road by myself once soon after school and my teacher (recognised the car) zoomed past, barely missing me, spooking my pony... you'd think she'd maybe slow down for a primary-school-sized child riding alone on a pony? We'd been doing road safety in class earlier that day...)
So, yeah, I'm sorry. Didn't mean to have a go.
Jousting always looked kind of tricky to me. How did you do?
