Definition :


Bats are mammals of the order Chiroptera whose forelimbs form webbed wings, making them the only mammals naturally capable of true and sustained flight. By contrast, other mammals said to fly, such as flying squirrels, gliding possums, and colugos, can only glide for short distances. Bats do not flap their entire forelimbs, as birds do, but instead flap their spread-out digits, which are very long and covered with a thin membrane or patagium.

Bats are the second largest order of mammals , representing about 20% of all classified mammal species worldwide, with about 1,240 bat species divided into two suborders: the less specialized and largely fruit-eating megabats, or flying foxes, and the highly specialized and echolocating microbats. About 70% of bat species are insectivores. Most of the rest are frugivores, or fruit eaters. A few species, such as the fish-eating bat, feed from animals other than insects, with the vampire bats being hematophagous, or feeding on blood.

More info about Bat Sounds :

As dusk advances you may be lucky enough to see bats, but as darkness falls you usually don't even know they are there.

There are lots of silly ideas about bats - like them getting tangled in your hair in the dark. This just doesn't happen - they are wonderful navigators in the dark, and manage this not with super-sensitive eyes (like owls) but by echo location - seeing by sound. Unlike birds, they do not fly into window glass because it is opaque in their sound world.

Drawing of Natterer's Bat

Basically they emit a 'chirp', and listen to the echoes. (Usually it is described as a 'click', but the slowed down recordings will persuade you that it is a sliding tone.)
From these echoes bats can build a rich 'picture' of the world about them. However impossible this seems, dolphins obviously share the skill. Try to explain vision to a person who has never had sight, and the difficulties of understanding a completely alien form of perception become clear.

But you hear dolphins calls, but you can't hear bats. Why not?
Humans can only hear sound up to about 16KHz (that's 16,000 cycles per second). Bats emit sounds at typically 2 or 3 times higher pitch than we can hear. Sounds above human hearing are usually called ultrasonic.
Whales and elephants can make sounds below what we can hear, about 16Hz (16 cycles per second), and these are called infrasonic.
