Why Do Bats Fly Only At Night?


Bats are small winged creatures and doesn’t need sunlight. They swoop at night between houses and plants with surprising speed, catching the inserts.

They avoid all kinds of obstacles by quick deliberate movements. A sixth sense guides them at night and helps them to ‘see’ the dangers and avoid them in time. This sixth sense works like our modern radar. As the bat flies, it emits a series of very shrill sounds.

When some obstacle gets in its way, these ultrasonic sounds are bounced back within fraction of a second. the bat hears, recognizes, calculates and keeps the obstacle away with a flap of it’s wings.


Below Bats info from Wikipedia (

Bats are mammals in the order Chiroptera (pronounced /kaɪˈrɒptərə/). The forelimbs of bats are developed as wings, making them the only mammals naturally capable of flight (opposed to other mammals, such as flying squirrels, gliding possums and colugos, that glide only for a distance). Bats do not flap arms like birds, instead they flap spread out hands where their fingers[2] are very long and covered with a thin membrane or patagium. Chiroptera comes from two Greek words cheir (χειρ) "hand" and pteron (πτερον) "wing."
