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.
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 >
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 >
Bats hang upside down to roost and sleep because the bones in their hind legs are lightweight and cannot support a bat's body weight in an upright stance. While they rest, bats wrap their wings around themselves like a cloak.Full Answer >
Bats are mammals, not birds, so they do not lay eggs. The female bat becomes pregnant after mating with a male, just as with any other mammal.Full Answer >
