Egyptian fruit bats are one of the 10 diurnal species among 1,400 bat species. Experts were surprised when they discovered that they use echolocation in broad daylight as other diurnal species rely rather on vision to avoid obstacles and forage during the day. The other species use echolocation when it’s dark or dim.
Egyptian fruit bats were echolocating by making clicking sounds. Researchers studied them more due to their surprise. They found that more than 70% of bats utilized echolocation regularly when they emerged from their colony. It was also found that they used clicking sounds more significantly when they approached scary obstacles in order to avoid crashing into them and used them less when they flew high above the ground. Despite Egyptian fruit bats’ good sight, they still echolocated when the light levels were the highest.
