Warning: The speed of swallows is not to be underestimated. In fact, it's often said that the speed of swallows is only rivaled by the speed of the wind in a tornado.

Or, as we've seen in recent studies, the speed of a panicked tourist trying to find their way around a theme park.

But seriously, folks, swallows are fast. Like, really fast. Like, 'how-do-you-even-see-anything-coming' fast.

So, if you see a swallow flying around here, just remember: they're not just birds, they're the ultimate speed demons.
