After seeing some stunning radar images, I spent about a 1/2 hour outside listening in my yard in Topsham last night, and vocalizing birds migrating overhead were very abundant. I also spent another half hour directly afterwards listening from my window.
The NFC's that I heard were led by Swainson's Thrushes (28 individuals) and Veeries (29), followed by a good number of Northern Parulas. Many were calls that I could not identify.
During roughly 1 hour of listening, I heard 154 birds call overhead.
So thrilling to hear -- this will never get old for me!
