Bats communicate with each other through echolocation, the use of very high-frequency sounds. Using sound enables bats to visualize objects of any size in their environment.Know More
Bats create sounds through their mouths, but some bats produce sounds through their noses. Their sensitive ears pick up the sound reflecting off the objects around them. They rely on echolocation not only for communication, but navigation as well. Echolocation enables them to recognize the size of any object.
Bats can also determine the distance of things based on the time it takes for the reflecting sounds to reach their ears. The bats emit consecutive, loud ultrasounds that fluctuate from a high to low frequency. This helps them easily identify and capture nearby prey and avoid obstacles in the way.
Bats generate an incredible rate of 200 pulses per second at extremely high frequencies that are largely inaudible to the human ear. The hearing range of humans is around 20 hertz to 15 to 20 kilohertz, depending on age. In contrast, bats are capable of hearing sounds up to 110 kilohertz in frequency.
More than 800 species of bats use varying frequency patterns. Different bat species use particular frequency ranges according to their surroundings and type of prey. Scientists can identify various species by listening to the sounds of bats using bat detectors.Learn more about Bats
Bats are nocturnal because they find bugs during the night, and they can evade predators more easily at night. Bats stay away from daylight to avoid competing for food with other predators, such as birds. Bats are also active at night because they cannot see very well during the day, and they rely on hearing and bouncing echoes to navigate during the night.Full Answer >
In times of low food supply, bats can choose to hibernate or migrate. Where bats live is dependent on the food supply available in a given area.Full Answer >
Bat flying speeds vary by the species, but they can range from 12 mph up to 40 to 60 mph. The Mexican free-tailed bat is one of the fastest, flying at speeds up to 60 mph.Full Answer >
Bats do have eyes. Fruit bats have very large eyes that help them navigate in deep darkness and find their preferred foods. It is only the group of bats known as Microchiropterans that rely mainly on echolocation, but even these bats have eyes.Full Answer >
