Silver Haired Bats
These are in abundance in North America. A colony can contain anywhere from 5 to 50 bats but they primarily enjoy being alone. They are medium sized and contrary to their name, their fur is black, not silver.
Bats play an important ecological role to flowers and many other plants as well as being essential in keeping the insect population down. A single bat is capable of eating 600 mosquitoes and other crop eating insects in an hour so gardeners and farmers love them.
