Although ultrasonic signals are used for echolocation by toothed whales, no known examples of ultrasonic avoidance in their prey have been found to date. [2] Ultrasonic hearing has evolved multiple times in insects: a total of 19 times. Bats appeared in the Eocene era, (about 50 million years ago); anti-bat tactics should have evolved then. [3]
Provides a comprehensive tool for analyzing and comparing high-resolution full-spectrum sonogram of bat echolocation calls recorded from time-expansion bat detectors. Sound Analysis Pro 2011 [9] GPL v2: Windows: Performs automated recording and analysis of animal vocalization. It can record, analyze and manage sound data over prolonged periods.

Principle of bat echolocation: orange is the call and green is the echo. In low-duty cycle echolocation, bats can separate their calls and returning echoes by time. They have to time their short calls to finish before echoes return. [95] The delay of the returning echoes allows the bat to estimate the range to their prey. [93]
Despite its scientific name, it feeds exclusively on fruits, nectar, and flowers, like the other flying foxes of the genus Pteropus. It is noted for being one of the largest bats. [ 4 ] As with nearly all other Old World fruit bats, it lacks the ability to echolocate but compensates for it with well-developed eyesight.
As a nocturnal species, little free-tailed bats primarily rely on echolocation to detect their prey and environment. [4] Since higher frequency of echolocation call attenuates with distance faster than low frequency, this species uses low frequency calls with high intensity, which last longer and thus are suitable for prey detection with long ...
Like other bats, leaf-nosed bats are nocturnal foragers that use echolocation to locate food sources, though the food sources vary between species. [14] Many bats in the family Phyllostomidae appear to have limited reliance on echolocation, likely because frugivorous bats do not need to quickly identify flying insects like many other bats. [ 8 ]
Its species name "pipistrellus" is derived from the Italian word pipistrello, which means "bat." The soprano pipistrelle, Pipistrellus pygmaeus, was formerly considered synonymous with the common pipistrelle. In 1999, [7] it was formally split from the common pipistrelle based on differing echolocation signatures and a genetic divergence of 11% ...
