—Human Echolocation, Bird Beauty, Lessons From Locusts “” Dolphins, pigeons, and locusts, oh my! Rather than retaining the negative connotation from Dorothy's original fear-of-animals version of that phrase in the "Wizard of Oz," a trio of new studies by scientists in Spain, Japan, and Canada is pointing to fascinating lessons that creatures in the animal kingdom have to offer one another. Echolocation, for one. Porpoises use this technique primarily to navigate the dark, murky ocean. But people can be trained to hone their own rudimentary ECHOLOCATION SKILLS into a better environmental awareness that enables them to distinguish, for example, the distance between a stand of trees and nearby pavement.
