Pre Dawn Thrush Flight 30 September 2014

I recorded over 310 thrush calls between 5am and 6:35am at my home in Hunterdon County, NJ this morning.  Here's the eBird checklist.

As always, there are many calls that I'm still puzzling over.  Here's a spectrogram of a call sequence from 6:09am:

Back in the NFC Saddle

This past spring I crashed the laptop I was recording night flight calls on, and I didn't get my MacBook Pro set up to record until last night.  But I'm back in business now thanks to my Griffin iMic adapter and Audacity software.  Still recording using the Oldbird 21c mic.  Since the Oldbird detectors aren't set up for the Mac, for now I'm just recording then browsing the spectrogram by hand to find and ID the calls.

Here's my eBird checklist from early this morning.
