All calls are presumptively identified as no birds were seen.
Gray-cheeked Thrush, typical calls, 4.45am

Buzzy variant, 5.10am

Gray-cheeked and Swainson's Thrush calls, 5.29am
Lower and higher calls, 4.56am


In this cut the gray-cheeked call is consistent with the appearance of Bicknell's, 11.53pm

A Swainson's Thrush variant "doubled" call, the bird using both syrinxes to create the sound, 9.43pm

A late Veery, 3.03am

An early Hermit Thrush, 2.45am

This strongly modulated call is similar in appearance to the buzzy Rose-breasted Grosbeak call as described on the Flight Calls DVD by Evans and O'Brien, 9.21pm

Another presumed Rose-breasted Grosbeak buzz, 10.59pm

The flight call of the Scarlet Tanager is a clear chu-wee, and seems to be less frequently heard at night than those of the thrushes,11.06pm

White-throated Sparrows began arriving in earnest in early October, 1.46am

Chipping Sparrow, 1.48am

Green Heron, 3.22am

American Bittern, 2.46am

This single owl wail may be an Eastern Screech-Owl, or possibly a Northern Saw-whet Owl; the call closely matches that on Cornell's Voices of North American Owls, Disc 2, cut 64.
11.48pm
