This is a brilliant idea. Last fall there was a big songbird night kill at gas
plant flares in New Brunswick (reported widely in the media, e.g.,
here<http://www.cbc.ca/news/canada/new-brunswick/7-500-songbirds-killed-at-canaport-gas-plant-in-saint-john-1.1857615>),
on a night when anyone following this or related lists would’ve seen that it
was a bad night to keep the lights on.
Just saying,

I have been trying to correlate flights as reported by NFC observations, and
radar with our experience picking up window strikes in DC. Last night's
reported flight in the northeast resulted in only a couple of warblers this
morning. I wonder if any other Lights Out groups are getting different
results? We should be able to declare emergency nights when we expect big
flights- if only we can correlate. -TATE

I can attest to the enormous flight in southwestern Pennsylvania this morning.
Still analyzing recordings but as a preview I am up to just shy of 900
Swainson’s Thrush calls in the last 30 minutes before civil twilight, along
with 51 Gray-cheeked, 15 Wood Thrush, and <10 Rose-breasted Grosbeak and
Scarlet Tanager. Warblers calls in total are at about 90. Still analyzing with
a long way to go, which will greatly up the totals of Swainson’s and
Gray-cheeked judging by what I heard in real time. Later in the morning I had
15 sp. of warbler at a local migration hotspot.
Last night was one of the most impressive flights I’ve heard here in suburban
and often noise-infested Pittsburgh.

Apparently there was a very large flight involving thousands of mostly thrush
calls over western PA last night and around dawn. I think it was much lighter
over eastern PA, as seems often to be the case. At Hawk Mt. in SE PA, a NE wind
of 5-8 mph was enough to rustle leaves and mask calls (only 20 or so heard
around 6 am), but I rarely hear many calls on windy nights even if there are no
trees to rustle. The calm night of 9/17 was much better at Hawk Mt., with over
500 calls in 20 minutes starting at 6 am, most Swainson's & Wood Thrushes (also
lots of Wood Thrushes calling in the woods after daylight), with 13 Gray-cheek
calls thrown in. I also rarely hear warblers in the dawn descent period, even
when I find good numbers of them in the area after daylight.

Andrew, et. al.,
I haven’t gone through all of my recording data from last night, but I have
certainly observed what you are mentioning: significant thrush vocalizations in
the minutes immediately leading up to the start of civil twilight. Often, after
midnight, there are very few warbler calls and equally few during the thrush
descent. Herons and bitterns seem to be vocal in the first three or four hours
of the night, and then wane after that. I’m not sure what the cause or purpose
is for this decrease in vocal activity in warblers after midnight.
Last night, there were hundreds of Swainson’s Thrushes and Rose-breasted
Grosbeaks calling, tens of Gray-cheeked Thrushes with a single potential
Bicknell’s Thrush candidate, a good handful of Wood Thrushes and Veeries in the
mix. No Hermit Thrushes. A couple of Scarlet Tanager candidates. At least one
American Bittern, two probable Least Bitterns (I’d like to discuss this later
on NFC-L) and several Green Herons. Two American Woodcocks flew by shortly
after the start of civil twilight, one stopping the wing twittering long enough
to utter some very soft and gentle buzzy squeaks
