With the onset of hot, humid weather, Bay State homeowners may discover bats residing in their homes. Because Massachusetts and other northeastern states are experiencing a sudden and unexpected decline of bat populations due to a white powdery fungus on bat faces called White Nose Syndrome (WNS), the Division of Fisheries and Wildlife (MassWildlife) is asking anyone with a summer colony of ten bats or more on their property to report that information to agency biologists. Little Brown Bats and Big Brown Bats are the most likely species to be found in buildings. Please report the colony's location, what kind of place it is in, and how many bats are in the colony, by calling (508) 389-6300, or email email@example.com. Everyone's response to this call will be greatly appreciated.
