Microbat

It has been known for many years that bats use echolocation to navigate and find prey in the dark. What has been left unanswered is how that when bats are flying together are not found running into each other due to interference of sound waves from their neighbours. It is known that bats do not have any problems with this interference because bats have been observed flying in swarms and capturing prey with not a problem. What scientists are now trying to discover is how the bats can get around the problem of interference. It has been hypothesized that the bats change the frequencies in response to other signals to avoid interference or “jamming”. Most previous research that had been done was basic observation of bats flying together. It has been shown by earlier research that the greatest difference in frequency came from bats of the same species when flying together, rather than flying at a large distance from each other. It has also been demonstrated in previous research that bats flying in a swarm alter the duration of their pulses. Another important discovery was that bats tend to avoid hunting in areas of “high ultrasonic background noise” an example of this is a turbulent stream or river. Additional factors that played a role in manipulating the signal frequency in bats is the environment in which they are hunting; whether it is open area, or forested. The Doppler effect must also be taken into account when looking at the frequency changes made by flying bats. The…

A mammal is a vertebrate organism with hairy body that give birth to live young and feed their young with mammary gland. Out of the 29 Orders of mammal, the Order Chiroptera (bats) is the only Order that can fly. Bats is the only mammal that have modified limbs allowing it to achieve the ability to fly (Hickman, 2015). Bats is also the only few mammals that have the ability to use echolocation- the ability to use high frequency sound to navigate the environments. Bats are divided into two…
