NJ Nocturnal Migration--15 October 2012

So last night there was a moderate amount of bird movement shown or NEXRAD in NJ and across the coastal NE states after the front moved through earlier in the afternoon and evening.

Note line of green storm clouds moving off the east coast, with bird migration behind it.

Between 7:10pm and 6:30am, my microphone autodetectors picked up 69 detections, all from the Tseep-X detector, as the thrush migration winds down.  Here are the first 63 calls (click for larger view):

As seen so far this week, mostly sparrows including White-throated Sparrow, Chipping Sparrow, and Savannah Sparrow.  Also still a few Common Yellowthroat (eg. 1C and 2F) and a Black-throated Blue Warbler (not shown).  Some of the calls (eg. 6C and 7D) are high pitched and faint, and I'm not sure yet what they are--perhaps waxwings or kinglets.  Stay tuned!
