How do bats hunt at night when they can't see in dark?
The traditional thinking
tells that bats come at night because they can see clearly in the dark but ,
this is however a wrong notion. Experiment done on bats tells that bats can fly
comfortably even if its eyes are covered by some opaque material. This was
possible because they use sound rather than sight to navigate. This
method of navigation is know as echolocation and it is similar in principle to
the sonar that submarines use to navigate the ocean. Some bats eat
fruit, many bats eat insects and vampire bats in the tropics feed on the blood
of animals. To search for insects a typical bat will sweep an area with
sound, sending out 10 beats per second. When the echoes come back from
the prey, such as a fly, the sound pulses increase to more than 25 per
second. This gives the bat a better idea of where the fly is
moving. As the bat near to its prey, it sends out more and more sound pulses
as many as 200 per second. Some bats are so good at echolocation that
they can detect and avoid wires as thin as human hairs.

ReplyDeleteI believe they use their senses to hunt, isn't it? I am not sure of it as this is just a wild guess. Kindly let me know if you get answer of it, thanks

ReplyDeleteAlthough bats are blind at night but they can hunt just because of their God gifted sound to catch their target. This is something amazing.
