Echolocation can be defined as a method of communication that is used by certain South Carolina animals in which they call out to the environment and listen to the feedback in the echoes from those calls that return to them. These animals use echolocation or bio sonar as it is commonly referred to, to hunt for food and look out for predators in the environment.



They can decide the distance between them and the possible obstruction in their path or even the size or shape of the obstruction based on the time taken for the echo to bounce back to them and the intensity of the echo.

Greenville bats are some of the animals that are able to use echolocation to navigate and hunt for their food. These animals have a good vision that they can also use but they are better adapted to use echolocation much more accurately. Through echolocation, a bat can be able to determine the distance and direction in which there could be a meal or possible obstruction its path from the time and loudness of the echoes that bounce back to them.

A Greenville bat can also be able to easily tell the size of the animal and some of its features as well as determine what type of animal it is. The bats can also determine how high or low an animal is through the interference patterns that are usually caused by the action of reflecting the echoes coming from them and landing onto the tragus; a part of the bats’ external ear.

Different bats are adapted to use echolocation differently depending on the kind of animals they hunt for their food and the environment in which they thrive. The science behind these echolocation calls however remains the same. This can also be said for the purpose of the echolocation calls. In all cases, the bats use this to find their food and detect their potential predators.

Some bats, commonly referred to as low-amplitude bats, have lower-register echolocation so as to prevent their prey that can pick up echolocation, the moth for example, can fail to detect them as they swoop in on them.

Bats use these echolocation calls to also communicate with each other. The mother bat will communicate with her young ones using very specific noises that only they will be able to understand. The same also goes for the male and the female bats during the mating season. Warning calls also sound different and are meant to warn of impending danger.

Echolocation calls also vary in the period in which they last. A bat that is still far away from its prey will make longer echolocation calls while the same calls will become relatively shorter as the bat closes in on its prey. The bat reduces the call period in order to prevent the vibrations that are bouncing back from overlapping with the call itself.

Echolocation in bats is of the utmost accuracy and enables them to survive in the night which is when they prefer to hunt as there are even less predators during that time.
