To actually go from detecting the insect to the capture, our eyes just don't take it.

This gives us a lot of insights we wouldn't be able to make using static images.

We have found that bats adjust the timing of their sounds when they encounter clutter, and they seem to 'strobe' the world with sound.

We found the bat, using its sonar 'beam,' looks ahead of where it flies, and that there is a relationship between how the bat moves and where the beam is directed.

When (the bat) gets an echo back, it uses features of the echo to tell how far away the bug is.

This species of bat has been observed capturing insects near the ground and vegetation, which suggests they have a wider repertoire of sonar-guided behavior than previously recognized. We thought the sonar strobe groups might be well suited to helping the bat distinguish a small object from the more complex background you would find in the wild.
