A short discussion of Massachusetts bats from environmental researcher Erin Ruggiano, followed by a live mix of bat echolocation sounds as they begin their evening forage, and whatever birds and amphibians may be winding down their day around dusk. 

Our intention with this event is to gather and mix these sounds as they happen at Massachusetts Audubon's Arcadia Wildlife Sanctuary, with a live stereo mix of bat detectors, air microphones, other sensors.
