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
Animal echolocation other, or both structures. An FM sweep is a broadband signal – that is, it contains a downward sweep through a range of frequencies. A CF tone is a narrowband signal: the sound stays constant at one frequency throughout its duration. Echolocation calls have been measured at intensities anywhere between 60 and 140 decibels. Certain microbat species can modify their call intensity mid-call, lowering the intensity as they approach objects that reflect sound strongly. This prevents the returning echo from deafening the bat. High-intensity calls such as those from aerial-hawking bats (133 dB) are adaptive to hunting in open skies.
