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.

Often, after midnight, there are very few warbler calls and equally few during the thrush descent.

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.

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?

RE: [cayugabirds-l] [nfc-l] Thursday: Night Flight in Northeast
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.
