![]() Bats can see better at night because they are nocturnal animals. In low-light situations, bats have exceptional vision. According to the researchers, they sped up echolocation when they landed after a flight, implying that they blend information from sight and sound to precisely judge distances. Researchers found that bats echolocate more in the dark but continue to make clicking sounds even in bright light, according to a 2015 study published in the journal Current Biology. The Egyptian fruit bat, little brown bat, Rousettus Aegyptiacus, and different species have excellent visual and echolocation (hearing) abilities. In many species, vision and echolocation bats appear to act in tandem. These animals have exceptionally keen visual abilities, with some even being able to see ultraviolet light. Many fruit bats don’t echolocate at all since they prefer to drink nectar rather than hunt insects on trees. In fact, researchers suggest that, depending on the situation, bats hunt with their eyes rather than their ears. On the contrary, given the ability to “see” with their eyes and hearing, they could certainly fly circles past most other creatures. We now know that the phrase “blind as a bat” was coined because people assumed these charming little vampire bats had poor vision. From their eyes to their ears to their flying and roosting habits, they are truly unique. Bats are fascinating mammals with elaborate designs that have evolved into a unique species. However, this does not rule out the possibility of bats seeing.īats are not blind. ![]() Can Bats See in the Dark?īats utilize echolocation for hunting in the dark, which means they use echoes of self-produced sounds bouncing off things to guide them. While this isn’t true, there is evidence that bats have a great hearing to compensate for their lack of vision. This has evolved into the more common “blind as a bat” expression that we are familiar with today.īecause of their chaotic, random flight patterns, which created the impression that they couldn’t see where they were going, people thought bats were blind. So, when and why did individuals start adopting this idiom?Īccording to legend, Aristotle was one of the first to allude to bats’ poor eyesight when he said, “For as the eyes of bats are to the blaze of day, so is the reason in our mind to the things which are by nature most plain of all,” almost 2,000 years ago. The phrase is commonly used as an insult to characterize highly unobservant persons (despite the fact that this has nothing to do with their visual acuity!). ![]() You may have even been called this by someone else. You may have described yourself as “blind as a bat” if you have poor eyesight or use glasses with a heavy prescription. Bats echolocate more in dark areas during dusk, but they also do so during the day. Their acute hearing allows them to detect echoes of this sound coming from insects, walls, and larger predators, indicating their location.īecause their eyes are small and have limited visual acuity, most smaller bats rely on echolocation to navigate and hunt, but larger bats have larger eyes and prefer to utilize their vision for these activities. When it’s light, they use their sight to find food, but they rely on their hearing and echolocation when it’s dark.Įcholocation is a remarkable phenomenon in which bats fly about making clicking sounds. “Bat brains must constantly integrate two streams of input, gathered with two independent senses, to form a single vision of the environment,” according to a study on bat behavior. To locate their prey, bats rely on a combination of hearing and sight. People now use it to describe someone who has bad eyesight or can’t see even the most obvious object. This notion about bats evolved into an idiom with several meanings. In reality, they employ a technique known as echolocation to explore huge distances. This is a figure of speech based on the belief that bats have poor vision.īecause of their meandering flight style, people thought bats were blind before the twenty-first century. When someone has poor vision, we can refer to them as “blind as a bat.” When it comes to its origins, it belongs to the category of animal-derived idioms. But what if the most basic truth about bats you’ve always been told isn’t true? What if “as blind as a bat” meant that you could see quite well? Why Do They Say Blind as a Bat? That, and their alleged blindness, which, according to legend, makes echolocation crucial for detecting and feasting on fruits, insects, and other small creatures. Have you also been wondering “ Are Bats Blind?” Bats are arguably best recognized for their capacity to “see” with their ears. It’s no surprise, given their echolocation ability. People see bats as supernatural, with vampires and even superheroes being associated with them. Bats are peculiar creatures with peculiar habits, such as occasional bloodsucking, sleeping upside down, and remaining awake all night.
