Summary:
New research helps elucidate how bats actually fly to find their prey. Every night a bat puts in 600-700 kilometres of airtime. Flying low, the animals catch insects at speeds of around 40 metres per second. At night the bat uses its hearing to navigate its way to prey. Bats catch insects continuously using echolocation, an advanced navigation system.
FULL STORY
New research, complete with night-vision video recordings, helps elucidate how bats actually fly to find their prey.
Every night a bat puts in 600-700 kilometres of airtime. Flying low, the animals catch insects at speeds of around 40 metres per second. At night the bat uses its hearing to navigate its way to prey. Bats catch insects continuously using echolocation, an advanced navigation system.
The bat emits ultrasonic waves with very high frequencies. Its calls are pitched at 20-100 kilohertz, a frequency that is too high-pitched for humans to hear naturally. Their sounds are reflected in the environment, hitting various objects and returning to the bat as echoes. The echo signals enable the bat to form a mental map of its surroundings.
Like using a flash
According to Nadav Bar, an associate professor at the Norwegian University of Science and Technology's Department of Chemical Engineering who has recently researched bats, "You can compare echolocation to using a flash in a dark room. The flash hits various objects in the room that light up and are reflected back to the eye of the observer. The bat uses sound in the same way to get an overview of the environment, but the potential sources of error are far greater when using sound."
Different daytime flying pattern When bats on rare occasions fly during the day, they use their vision to navigate and fly in a straight line to their destination.
Explanation:
Answer:
They are one of the few mammals that can use sound to navigate--a trick called echolocation. Of the some 900 species of bats, more than half rely on echolocation to detect obstacles in flight, find their way into roosts and forage for food. ... Most bats produce echolocation sounds by contracting their larynx (voice box).
