Bats in flight can distinguish the difference in sound between a tree, your head, and a tasty grasshopper. Bats are not blind, but most have better night vision than day vision. They see in black, white, and shades of gray. Some male bats sing to attract a mate. Females have only one pup per year, although twins or quadruplets occur in a few species.
Some tropical bats can have two pregnancies a year.
Mothers nurse their pup for two to six months, then teach it to fly and find food. Their hair catches pollen and carries it from flower to flower. Many plant species would not survive without bat pollinators. This micro bat leaves its cave about two hours after sunset to look for grasshoppers, cicadas, moths and beetles. It also feeds on fruits, including cacti.
