Honduran fruit-eating bat Neotropical bats, which typically range from 10-85 g. It displays the characteristic lack of tail and narrow patagium seen in fruit bats, and also has a very densely furred uropatagium, which distinguishes A. hirsutus and A. inopinatus from many other species in the genus. Like most bats, they are nocturnal, roosting during the day, and use echolocation for navigation at night. The bats are in the family Phyllostomidae, also referred to as the New World leaf-nosed bats. This group tends to have distinct pointed, or "leaf shaped" snouts which assist them in echolocation. The Honduran Fruit Eating bat has a
Human echolocation since at least the 1950s. In earlier times, human echolocation was sometimes described as "facial vision" or "obstacle sense," as it was believed that the proximity of nearby objects caused pressure changes on the skin. Only in the 1940s did a series of experiments performed in the Cornell Psychological Laboratory show that sound and hearing, rather than pressure changes on the skin, were the mechanisms driving this ability. The field of human and animal echolocation was surveyed in book form as early as 1959. See also White, et al. (1970) Many blind individuals passively use natural environmental echoes to sense
