Using a Sonic Net to displace birds from target areas: applications to reduce bird-strike
Presenter: Dr. John Swaddle, William and Mary University
Birds are inherently vocal animals. They use calls and sounds to communicate about social interactions, mating, finding food, and avoiding predators. A Sonic Net produces a sound that masks all of this important information for birds, by delivering a loud noise over the same frequency ranges that birds communicate. When given the opportunity to move to an area where the Sonic Net is not present, I will talk through several field examples where this technology has been deployed and reduced the presence of birds by 80-90%–including in an airfield environment. The Sonic Net does not harm birds. Rather, it greatly increase the birds’ perception of predatory threat and renders a target environment uninhabitable while the sound is deployed. There are no indications of habituation as the change in perception of risk is real and does not diminish over time. Hence, the Sonic Net could be a long-term solution that can help with reducing bird-strike at airfields.
Professor John Swaddle is the Faculty Director of the Institute for Integrative Conservation at William & Mary. He received his BSc and PhD from the University of Bristol, UK. His research program focuses on designing practical solutions that help to harmonize wildlife conservation with the enhancement of livelihoods and wellbeing of people. He has published more than 100 peer-reviewed articles and received over $25m in external funding. John has been awarded several prizes by his international academic societies and is past-President of the Animal Behavior Society. At W&M he has served as the Dean of Graduate Studies and Research, was the Director of the Environmental Science & Policy program, and is co-Chair of the university’s Committee on Sustainability and Climate Action Plan Committee. He has consulted for Fortune 500 companies and regularly works with industry partners to reduce the risk of collisions for birds.
Avian radar use for wildlife control at two Canadian airports, YVR and YYZ
Presenter: Dr. Tim Nohara, Accipiter Radar
Vancouver International Airport (YVR) and Toronto Pearson International Airport (YYZ) have begun to use avian radar to better understand bird activity and automatically alert wildlife control personnel day and night to areas on and off the airport with significant bird congestion that increases the risk of bird strikes. The seminar will present real avian radar data to illustrate bird activity situational awareness, risk alerts, control actions in response to risk alerts, and their effectiveness on dispersing hazardous birds.
Dr. Tim Nohara is the President and CEO of Accipiter Radar, pioneers of affordable avian radars now in use at civil and military airports around the world to help aviation stakeholders reduce the risk of bird strikes. He received a Bachelor, Masters and Ph.D in Electrical & Computer Engineering from McMaster University in 1985, 1987 and 1991 respectively, is a licensed professional engineer and a senior member of the IEEE. He is the author of a number of peer-reviewed technical publications and patents on avian radar. Tim is a director of BSAC Inc. and has been an active member of Bird Strike Committee Canada.
All sessions will be presented on Zoom. Seminar time is given in Pacific Daylight Time. Please adjust for your time zone. Note that Pacific Daylight Time is 7:00 hours behind Coordinated Universal Time.
