In all our stewardship and restoration of natural areas, it’s easy to forget the way the world changes after the sun sets. Whether for additional data collection or as unique community engagement events, surveying natural areas at night can provide a wealth of information that would otherwise be missed or ignored. This presentation will focus on bats, owls, and flying squirrels, including techniques and tricks for acoustic surveying of bats and owling methodology. We will also dive into the basics of astronomy, including picking an observation site, major constellations and noteworthy astronomical objects, and how to find things in the sky from the Great Lakes region.
