October Movie of the Month

Meet the Coywolf

Stop by the Visitor Center during regular hours to see our new movie of the month. The Coywolf, a mixture of western coyote and eastern wolf, is a remarkable new hybrid carnivore that is taking over territories once roamed by wolves and slipping unnoticed into our cities. The story of how it came to be is an extraordinary tale of how quickly adaptation and evolution can occur, especially when humans interfere. Tag along as scientists study this top new predator, tracking it from the wilderness in Ontario’s Algonquin Park, all the way to the streets of New York City.. (Runtime: 55 minutes).

Friends Monthly Presentation: Monitoring for Bats at Mashpee NWR - Presentation by Eileen McGourty

October is the perfect month to learn about bats! Join us to find out about the bats that live in Massachusetts and how we benefit from their presence. Whether you have a fear of bats or an appreciation for these amazing creatures this program is for you! Eileen McGourty will talk about how we monitor for bats at Mashpee NWR including acoustic monitoring and mist netting. You will see photos from our mist netting project that has been conducted at Mashpee NWR over the past three year and learn about bat acoustics and how we can identify bats from their echolocation calls. She will also discuss white-nose syndrome and its impacts on bats, and a bit about bat behavior. If bats are still active in the area we may also step outside and try out some of our own acoustic monitoring!

Eileen McGourty is a Wildlife and Fisheries Biologist for the U.S. Fish and Wildlife Service stationed at the Eastern MA National Wildlife Refuge Complex. She began her career with the Service as a seasonal law enforcement officer at the Rhode Island National Wildlife Refuge Complex and after several seasons as a refuge officer became a seasonal biological technician working with plovers and terns. In 2001, she came to the Eastern MA National Wildlife Refuge Complex, working as an interpretive park ranger, and in 2004 became a permanent biologist. Current projects she is involved with include New England cottontail monitoring, acoustic bat morning and mist netting for Northern long-eared bats, and invasive species monitoring and control.

Our monthly presentations are usually held the 4th Wednesday of every month at 7:00 PM at the Visitor Center at the Assabet River NWR.
