This free webinar will explore how bioacoustics is used as an accepted survey technique for owl presence. The focus will be on deployment methods, best-practices, and data analysis. Case studies will be used to illustrate the benefits of using a wildlife audio recorder for owl monitoring. No previous experience is required for this webinar.
Read about Damon Lesmeister, Supervisory Research Wildlife Biologist with the US Forest Service, and his efforts to provide valuable information about the threatened Northern Spotted Owl using Song Meters for the stewardship of healthy and sustainable ecosystems
"Passive acoustic monitoring using autonomous recording units (ARUs) is a fast-growing area of wildlife research especially for rare, cryptic species that vocalize. Using demographic information about known Northern Spotted Owls, we found that weekly detection probabilities of Northern Spotted Owls were higher when ARUs were closer to known nests and activity centers and when owls were paired, suggesting passive acoustic data alone could help locate Northern Spotted Owl pairs on the landscape. These results demonstrate that ARUs can effectively detect Northern Spotted Owls when they are present, even in a landscape with high Barred Owl density, thereby facilitating the use of passive, occupancy-based study designs to monitor Northern Spotted Owl populations."
