Do Bats Need Echolocation to Survive?

It is a common misconception that bats are blind and must use their echolocating abilities to navigate around at night, and basically survive in general. Although there is some truth in echolocation abetting navigation, however, bats are not blind and can see just fine. Even non-echolocating bats in the Megachiroptera suborder have pronounced visual cortex that give them great sight and depth perception. Although bats are not blind, echolocation is a vital resource for microbats, and provides them with benefits that sustain their lives.

Bats and Echolocation

Echolocation is also referred to as “biosonar”, and is a utilized by bats in the Microchiroptera suborder, also known as “microbats.” It is a built-in biological system that works by measuring the returning echoes of emitted signals that bounce off surrounding objects. Echolocation is made possible through vocalizations that are produced by the larynx of microbats, but released through mouth and nostrils. There are a few species of Rousettus in the megabat suborder that use a similar sonar system to microbats, but in contrast to producing sounds in the larynx, they produce sounds by clicking their tongues. See our blog, “The Basic Principles of Echolocation in Bats” to learn more.

How it Echolocating Works

When bats use echolocation, they emit signals in ultrasonic pulses over 15 kilohertz which then travel through the air and bounce off of surrounding objects. Bats analyze the returning sounds to identify the objects and assess the distance between them. The type of signals and sounds emitted by echolocating bats differ among species in many aspects, including frequency, length of call, intensity, and degree of modulations. Many animals aside from bats use this type of built-in sonar system, including species of dolphins, porpoises, toothed whales, Killer whales, dwarf sperm whales, shrews, and some species of bird.

The Purpose of Echolocation

Bats can see, but echolocation gives them a superior advantage when it comes to hunting and diving for prey at night. Bats are insectivorous, which means they primarily eat insects that are small and fact, like moths, flies, mosquitoes, beetles, and more. With echolocating abilities, they can more accurately dart, dive, and dash for their prey when it’s dark. It also helps them navigate their way around dark caves and roosting areas. Think about it from this perspective: You can see just fine, but you can’t see very well at night. Bats are the same way, but they have a built-in sonar system that makes up for this disadvantage!

The Basic Principles of Echolocation in Bats

By now, you are well-informed that bats are not blind. In fact, they see quite well. Their echolocating abilities are more than just a visual guide; they are a biological instrument that provides an advantage in many areas of Microchiroptera bat life. Here in this blog, you will learn the fundamental facts surrounding echolocation and bats, including which bats are not equipped with natural echolocating abilities.

What is Echolocation?

Dictionary.com defines echolocation as, “the general method of locating objects by determining the time for an echo to return and the direction from which it returns, as by radar or sonar.” But in terms of animals, like bats, they better define it as, “the sonar-like system used by (…) animals to detect and locate objects by emitting usually high-pitched sounds that reflect off the object and return to the animal’s ears or other sensory receptors.”

In plain language, echolocation is like sonar, in that you let out a sound wave, wait for the sound wave to come back to you, and then use that data to define an environmental guide for whatever application you need.

Bats are not the only animals who use echolocation; dolphins and whales are well-known echolocating species, as well as, some birds and species of shrew, and possibly even hedgehogs, are suspected of using the same type of biological gift. For these animals, the primary purposes of echolocation are coordination and direction, evading obstacles, hunting or obtaining food, and interacting socially.

How Does it Work?

Although it is not yet fully understood by the scientific community how echolocation in bats works, but we do have a basic theory. Scientists and researchers have ultimately determined that bats have built-in vocal chords that vibrate when they move air past them.

They emit these extremely high-pitched sounds from their mouths (or sometimes noses) as they fly, which in turn, travel through the air as a sound wave. These traveling sound waves have energy that bounces off anything it comes into contact with.

After emitting these extremely high-pitched sound waves, bats listen carefully for their return, and use the time data to configure their surroundings more precisely. They use this to dart and dive for flying insects, better navigate obstructions, and more.

Interesting Facts About the Little Brown Bat

Little Brown Bat (Myotis lucifugus)

The Little Brown Bat is one of the most common species of bat found around Kentucky. Not only do they provide several economic and ecological benefits for our society, they are very interesting to learn about.

Continue reading to review some basic information about Little Brown Bats, including their scientific name and classification, as well as, their diet, range, habitat, and more!

The Little Brown Bat

Little Brown Bats are microbats, meaning they are nocturnal, generally small, and primarily retain an insectivorous diet of insects and other bugs. They can consume 50% of their weight in insects! And during gestation or lactation, they eat even more. Breeding season is generally around September and October, but females actually store the male sperm for springtime fertilization, making baby bats born in the summer. Gestation is generally 50 to 60 days, and once born, sexual maturity is reached between 6 and 8 months. Females generally give birth to just one bat pup a year, but sometimes two.

Physical Description

The Little Brown Bat, sometimes referred to as Little Brown Myotis, is scientifically named Myotis lucifugus. Myotis refers to a “mouse-eared” genus of bat. They are among the most common bats found in North America. Above, they are covered in shiny brown, sleek-looking fir, with a lighter patch of fir below. They are usually around 3 to 3 ½ inches in length and weighing only a fraction of an ounce, between 1/8 and ½ ounces. So needless to say, their name says it all because they are little for sure! Although small, their average wingspan will surprise you, as it is more than double their body length, averaging between 6 to 8 inches in width. But what’s even more interesting is that they can live up to 30 years or more, average between 20 and 30 years specifically.

Echolocation

Little Brown Bats use a system of sonar called echolocation, combined with their acute sense of hearing, to locate and hunt down prey. Echolocation is a natural built-in sonar system for bats. They send off sounds that make a mental-grid of their surroundings by bouncing off objects and returning to the bat. They also communicate with one another through a complex series of chirps, beeps, and high-pitches sounds; most of which are not detectable by human ears.

Range

The geographic range of the Little Brown Bat species includes 37 states, as well as, Southern Canada east of British Columbia. Part of this range includes Kentucky. They are often found roosting in the Northern parts of the state, also as their name suggests. Additional U.S. states include Alabama, Arkansas, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Vermont, Virginia, West Virginia, Wisconsin, and Wyoming.
