Echolocation and Vision
A study confirmed that bats, when they are able to see, prefer to use their vision over echolocation. In the experiment, these bats were put in a mesh greenhouse and observed at dawn, day, dusk, and at night. The bats consistently ran into the ceiling and walls of the greenhouse at dawn, day, and dusk while trying to fly out, but at night when they were forced to rely solely on the echolocation, they avoided the ceiling and walls without a problem. The pulses emitted by the bat are all audible to humans, and the bat only emits pulses through the mouth.

Famous quotes containing the word vision:
“For what we call illusions are often, in truth, a wider vision of past and present realities—a willing movement of a man’s soul with the larger sweep of the world’s forces—a movement towards a more assured end than the chances of a single life.”
—George Eliot [Mary Ann (or Marian)
