Joe Gyekis is a health science instructor at Penn State and an enthusiastic lifelong birder with particular interests in patch listing, nocturnal flight calls, and bird-window collisions. 

Joe will talk about recording bird migration from his suburban home at night for the past 8 years as well as observations from other Pennsylvania nocturnal flight call (NFC) recording friends, including fun rarities, interesting discoveries about migration timing, and which species are consistently easier to find by NFC than normal daytime birding.
