Vampire bats were not studied in their natural habitats until about 1935. During predation, bats first spend a few minutes in the air circling the target prey, eventually landing on the back or neck crest of the animal, and sometimes the ground. They then proceed to search for a suitable spot to bite, which can take seconds to minutes, and ...
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
