rationale is that birds don't really 'need'

Pretty fascinating stuff- since the radar reflectivity did not indicate the
'largest' flight of the season for NY State, yet the call rates were clearly
highest. The upper-level winds were out of the WSW last night, which may
have caused 1) more birds to compensate for drift and 2) birds to fly at

Thurs night, if the forecast holds. From a very local perspective, I think
this will result in the classic big and bigger morning flight at

Winds are indeed interesting. Several questions arise:
Do birds use surface winds to "decide" whether to go or not, or do they use
a combination of surface variables such as barometric pressure, rH, etc.,
and/or how much do they "test the atmosphere" (we do know that this occurs,

Hey All- I just checked the radar and it looks like a pretty heavy flight
over the Northeast US, the northern tier of the middle-states (northern
Central and Mississippi Flyways) and the Southeast (especially the
Southeast!). Is there anyone out listening tonight? The skies are pretty
cloudy here
I just got in from an hour of moonwatching with Brian Clough, where we
counted 62 birds between 8:55pm and 10:25pm (we counted over six ten-minute
periods between those two times). There were many birds calling overhead,
but neither of us could get beyond "sparrow-like" and "warbler-like". No
night for the Eastern Flyway, depending on which forecast
model you check).
The full moon is on Sunday, October 4th, so moonwatching conditions should
be excellent (assuming a clear sky) over the next 8 days.
