Week Five: Brown Bag Lecture

"Acoustic Monitoring of Nocturnal Bird Migration"
Speaker/Guide: Bill Evans

Director of Old Bird, Inc. co-author Flight Calls of Migratory Birds
Location: Smith Wilkes Hall

While we sleep, large waves of migrant songbirds pass over our homes during spring and fall migration. Many utter short vocalizations while in nocturnal passage to seek or maintain contact with one another. Bill will share over 30 years of studying this phenomenon of the intriguing and rarely heard vocalizations. Showcased will be fascinating migration patterns determined from the first five years of nocturnal flight call data across New York. Based on these results he will discuss the method’s unique potential for long-term population monitoring, public education, as well as the joy of tuning into the flights from our homes.

 


Bill Evans is the director of Old Bird Inc., a nonprofit focused on nocturnal bird migration research and education. He has studied avian nocturnal flight calls across North America for more than 30 years, and his work has been featured in many media, including PBS’s Nova, the BBC, NPR, Science, The New York Times, and the new documentary on songbird decline, The Messenger. He is co-author of the CD-Rom Flight Calls of Migratory Birds. 

A resident of Ithaca, New York, Bill is also involved with research toward understanding the impact of artificial light on night-migrating birds and their concentration dynamics along shorelines and in mountainous terrain. His expertise has led him into active involvement with efforts to mitigate avian fatalities at communications towers, wind turbines, and oil & gas drilling operations.
