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 liveliness of literature lies in its exceptionality, in being the individual, idiosyncratic vision of one human being, in which, to our delight and great surprise, we may find our own vision reflected.”
—Salman Rushdie (b. 1947)
