Is That A Lark I Hear? A Nightingale? Surprise! It's A Bat

Bats produce "pings" or "clicks," right? They make these high-pitched sounds, too high for us to hear, but when their cries ricochet off distant objects, the echoes tell them there's a house over there, a tree in front of them, a moth flying over on the left. And so they "see" by echolocation. That's their thing. They are famously good at it. We all know this.
But now, I want to tell you something you may not know.
