Bats Are Not Blind
Animal Fact No. 1: Bats are not blind. In fact, they have separate vision capabilities for both day and night sight. The fact that they navigate with echolocation simply describes a third way they can "see." So the next time we are tempted to say that a person is, "blind as a bat," we might want to rethink that colloquialism. Bats are also tremendously helpful to other species. Each one can eat up to a thousand mosquitoes in a single hour! If these little guys live near you, you may be able to use the repellant less often!
