Thought I would share this eBird list from the other night (Monday night). 
These are estimates, or specific call counts, of night migrants heard or seen 
flying in the airspace around Schoellkopf Stadium at Cornell University in 
Ithaca, NY. That night was nowhere near the epic night migration on 11 October 
2005, as described in this Wilson Journal of Ornithology article: (not sure everyone has access to view…). 
There were no birds visibly in distress. If anything, calling rates were simply 
higher around the ambient light reflecting off the low foggy cloud ceiling.

Good night listening!

Protocol: Stationary

Comments:     Excellent night migration. Predicted, suspected. Low foggy cloud 
ceiling, bright ambient lights at Schoellkopf Stadium. No practice or game, so 
little other acoustic disturbances for listening. This was the second best 
night migration I have personally experienced at this locale. Numbers are not 
call counts, but best estimates of numbers of individuals. Extremely 
conservative. Actual call count could easily be quadrupled or more. Very few 
birds continued to circle around more than once, if rarely twice; most could be 
heard audibly transiting over this area, with calling rates increasing while 
over brightly lit area. Once lights were extinguished, all calls ceased 
12 species (+3 other taxa)

Gray-cheeked Thrush  48
NFC 48 | extremely conservative estimate of number of individuals.

Swainson's Thrush  102
NFC 102 | extremely conservative estimated number of individuals.

Wood Thrush  2

sparrow sp.  2
NFC 2 | one possibly was White-throated, but uncertain.

Common Yellowthroat  4
NFC 4 | distinct individuals

Cape May Warbler  5
NFC 5 Distinct night flight calls from this species heard directly overhead 
with several minutes between calls.

Bay-breasted Warbler  1
NFC 1 | Loudly calling individual, later observed flying and foraging in 
enclosed portion of upper Crescent. Logan confirmed visual ID.

Chestnut-sided Warbler  2
NFC 2 | audibly distinct calls from this species.

Blackpoll Warbler  6
NFC 6 | observed birds flying low, visible in the lights as well as foraging in 
ambient lit treetops. Majority of warbler NFCs were likely Blackpoll zeeps.

Black-throated Blue Warbler  12
NFC | 12 estimated number of distinct individuals

warbler sp. (Parulidae sp.)  205
NFC 205 | this is an extremely conservative best estimate of individuals 
passing through the stadium area during this count period. Likely hundreds more 
in broader audible range.

Scarlet Tanager  3
NFC 3 | distinct "pew-weet" or "pee-vee" calls from this species, audible 
during earlier time of listening period.

Rose-breasted Grosbeak  5
NFC 5 | audible clear squeaky "eek" notes heard during earlier portion of count 

Indigo Bunting  2
NFC 2 | clearly musical sounding buzzes heard of a group of individuals 
occurring over a short time span

passerine sp.  1
NFC 1 | particularly intriguing low frequency sounding ringing buzz, 
reminiscent of the overlap of Indigo Bunting and Blue Grosbeak flight call. 
Beefier sounding. Around 21:02. Recorded.
