Unfortunately for the bat they are not fuzzy and cuddly, so they do not sit high on the list of popular mammals. In the U.S. alone there are approximately 45 different species of bats. These nocturnal mammals can live up to 30 years, and have been known to migrate or hibernate when living in the cooler temperate zones. Their young develop rapidly and are able to fly within a few weeks. This echolocation allows them to navigate and sense object distances in the dark.
Many people fear a bat getting trapped in their hair, which is considered to now be a myth.
With such a complex sonar system, it is not realistic to believe they will just fly into your hair. Obviously in an enclosed place like a bedroom, and feeling threatened or injured they could be forced into this type of a situation. People who observe bats notice their seemingly erratic pattern of flying. This is a result of one of their feeding methods, in which they scoop insects into the fold of their wings and then feed upon them. Surprisingly enough, the bones in our hands and fingers are very similar to that of the bat, only theirs are longer.
