So, what's interesting is that you have this temporal modulation and this exists within the call and it basically provides some sort of kinetic data, right? So it acts like a verb. And the rate at which a chirp is produced correlates directly to the predator's speed. An increasing frequency and tone with a coyote call, that actually signals that the predator is running. So if you get a call that's a slower chirp rate, that means that the coyote would be merely walking. And the data contained, the density of the data in the chirps is actually compressed. So a prairie dog's chirp, it only lasts one tenth of a second, but within that one tenth of a second, all this complex information is packaged into what we would consider the equivalent of a human sentence and it's sent out. And that's where we get back to a tall thin human wearing a blue shirt walking slowly across the call.
