Last night between rain spells, Matt Medler heard some zeeps out the 
window. We went outside to listen and there was a constant stream of 
Swainson's Thrushes flying overhead. We hooked up the night flight 
recorder and were able to detect some 20 Swainson's in an hour's time 
as well as some warbler zeeps. Most of the "hits" were water drops 
off the trees, but the sonograms of actual bird sounds were obvious. 
We could hear additional birds that didn't get picked up by the 
microphone. A friend of ours in Maine also noted a heavy migration 
event last night at the same time. It was our first time using this 
technology and we're already hooked enough to keep it going during 
the migration season.  Stay tuned for more.....
