Bats are NOT BIRDS , 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, glide rather than fly, and 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.
THE BIBLE IS TOTALLY WRONG
Bats in the Bible: Leviticus 11: 13-20 (New International Version)
13 "These are the "BIRDS" you are to detest and not eat because they are detestable: the eagle, the vulture, the black vulture, 14 the red kite, any kind of black kite, 15 any kind of raven, 16 the horned owl, the screech owl, the gull, any kind of hawk, 17 the little owl, the cormorant, the great owl, 18 the white owl, the desert owl, the osprey, 19 the stork, any kind of heron, the hoopoe and the bat, 20 " 'All flying insects that walk on all fours are to be detestable to you.
The Bible categorizes the Bat among the "BIRDS" in the list of unclean Birds. also in Deuteronomy 14:11-19 (New International Version), Isaiah 2:19-21 (New International Version)
