Bat Week Oct. 24 - 31

Posted

Bat Week is an internationally recognized celebration of the important role bats play in our environment and a great time to appreciate New York’s bat species. Bat Week is observed Oct. 24 through 31.

Of the nine bat species found in New York, six are cave bats, meaning they hibernate in caves and mines throughout the winter, while the three tree bat species migrate to warmer areas. Since 2006, cave bats in the state have been devastated by a fungal disease known as White-nose syndrome (WNS). For example, Northern long-eared bats (Myotis septentrionalis) have faced 99% population declines due to WNS and are now federally and state listed as endangered. Recently, scientists have found some evidence of recovery of the once-common little brown bat (Myotis lucifugus). While this seeming stabilization provides a hopeful outlook after a devastating 90% population decline, similar evidence of stabilization has not been seen for other severely affected bat species.

To help, protect New York’s bat populations by avoiding caves and mines, which may be home to hibernating bats, from November through April. WNS makes bats very sensitive to disturbances during hibernation, and human activity can be particularly disturbing, causing them to use up their energy stores too quickly before spring. Even a single, seemingly quiet visit can kill bats that would otherwise survive the winter. If you see hibernating bats, assume you are doing harm and leave immediately. Anyone entering a listed bat hibernation site from Nov. 1 through April 30 may be subject to prosecution. Other ways you can help bats:

• planting a pollinator garden to increase prey availability for bats, who feed on insects;

• putting up a bat box on your property to offer bats a summer roost, safe from predators and human activity; view options for bat box designs and DIY at www.batcon.org/about-bats/bat-gardens-houses; or contact a bat certified Nuisance Wildlife Control Operator (NWCO) when looking to remove bats safely from your home.
