Bats in Colorado use echolocation to find and catch insects. If a bat is flying near you, it may be catching insects that you have been attracting. Those bats are helping you out. It is a myth that a bat is a flying mouse. Bats are sometimes small and brown, but they are not rodents.
Bats are also the only mammal that has evolved true flight.
Some bats are adapted to quick flight, flying over 40 miles per hour. Others are adapted to slower, more maneuverable flight. The oldest fossil of a bat is 60 million years old. The fossil bones show that they were already developed like today's bats. Please send comments, questions or requests for more information on this subject to wildlife .
