Last Friday night (2019-09-27/28) I had a reasonable successful recording of the night migration over my Solvang backyard. Most notable was the large number of thrushes that could be heard at sunrise. Between 7 and 7:30AM I had at least 20 SWAINSON'S THRUSH and a handful of HERMIT THRUSH.
If your neighborhood is quiet enough it should be possible to hear and distinguish the upslurred "wee" of the Swainson's and the downslurred/monotone "teer" of the Hermit Thrush. See/hear here for a comparison:
Other night flight calls that I managed to ID so far are: CANADA GOOSE, SAVANNAH SPARROW, SONG SPARROW, and DARK-EYED JUNCO. There is still a lot of stuff that I have to decipher though.
