Infrared Video: 500,000 Bats Emerge From Cave

"Bats use echolocation to see in the dark, but unfortunately human scientists cannot do the same.
That poses a problem for ecologists who want to know, for example, how many Brazilian free-tailed bats live in the Carlsbad Caverns of New Mexico. Researchers can’t shine a light on them because that disrupts their behavior, but they can’t see them without light. The answer? Infrared cameras, of course..."

Thermal Bats

That's an interesting video. I wonder why they used thermal IR instead of near IR? I wonder why they could not use echolocation to identify each bat? I would think that each bat should be identifiable from its voice.

I imagine that's what it's like to film what's going on in my testicles.

With that exact same music.

I have to say, that thought never occurred to me.
