NJ Nocturnal Migration--13 October 2012

Migration slowed recently, and the switch from warblers to sparrows in the mix is almost complete.  On 13-14 October 2012 the autodetectors located 68 calls, including

Tseep-X: 3
Thrush-X: 60
Other: A series of finch calls (1A-1E)

Here are most of the calls:

Note mostly White-throated Sparrows, with a few presumed Savannah Sparrow (2H, 4A).  Thrushes appear to be Swainson's Thrush (1F, 1G, 1H).
