NJ Nocturnal Migration--10 October 2012

So last night NJ had some pretty heavy winds from the WNW, up to 15 mph or so, making night flight call recording a bit difficult at times, and perhaps limiting some of the migration.  Here's the wind map at midnight.

On NEXRAD you can see what looks like a few birds in the air in western NJ (arrow), though migration was light across most of the NE and heavier in the SE and Midwest.

My recording station at home in Hunterdon County picked up a light migration.  I listened from 8:43-mindnight and heard mostly a few Tseep calls, Black-throated Blue Warbler, Savannah Sparrow, and Swainson's Thrush.

Tseep-X and Thrush-X autodetection software located a total of 73 calls, including:

Thrush calls:  3 (all appear to be Swainson's Thrush)
Tseep calls:  68
Other:  1 possible heron call

Here are most of the bird calls detected by Tseep-X and Thrush-X software as viewed in the Oldbird GlassOFire software.

Some initial quick IDs:

Swainson's Thrush calls (1B, 1D, 1E)
Ovenbird (2A)
Savannah Sparrow (1H, 5C)
Black-throated Blue Warbler (4B, 4C, 4F, 4G, 4H)
White-throated Sparrow (5H, 6G, etc.)
Northern Parula (7I)
Common Yellowthroat (2C, 3D)

Some of th eothers are faint or unclear.  Not sure what the tseep calls including 2B, 3B, 3F.  Blackpoll Warblers are still moving through in small numbers, so that might be the most likely candidate.  3G might be a Bay-breasted Warbler.  I'll have to take a closer look at the double-banded upsweeps at 2E and 6B--might be Tennessee Warbler.

Warbler numbers are declining, and sparrow numbers are climbing.  Hoping for better wind conditions and migrant passage tonight.
