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:
“The difference between human vision and the image perceived by the faceted eye of an insect may be compared with the difference between a half-tone block made with the very finest screen and the corresponding picture as represented by the very coarse screening used in common newspaper pictorial reproduction. The same comparison holds good between the way Gogol saw things and the way average readers and average writers see things.”
—Vladimir Nabokov (1899–1977)
