Zoom Webinar – The Fascinating World of Bats

March 25, 2023 at 4:00 pm - 5:00 pm PDT


On Saturday, March 25th at 4 pm via Zoom, Dr. Joseph Szewczak will discuss his investigations into the extraordinary physiological capabilities of bats, from cold torpor to the intense demands of flight and high altitude and bat distributions.  He will also speak about the need for software to study vocalizations both in birds and bats without having to resort to invasive techniques.

To successfully accomplish this, Dr. Szewczak developed SonoBat and SonoBird software.  He will also discuss his new research that has led him and a team of colleagues to take samples from bats to evaluate food webs and trophic levels along the Merced and Tuolumne Rivers in Yosemite National Park.  Join us for a fascinating lecture on the world of bats.

About the speaker:  Joseph Szewczak is Professor of Biology in the Department of Biological Sciences at Cal Poly Humboldt in Arcata, California.  He is a prominent name in bat research for a variety of studies, but holds the greatest distinction as the creator of Sono Bat.  SonoBat is a system that usesultrasound recordings of bats to identify species, eliminating the need for the more problematic mist nets.  He also created SonoBird to analyze bird vocalizations.  He began working with bats 33 years ago investigating the physiology of torpor and transitioned from the lab to fieldwork and echolocation.
