All,
I had been having similar thoughts to Chris: can we quantify the impact of
individual fallouts (or a series of fallouts) at a population level.
*However*, I worry quite a lot about using NFC or banding station counts to
quantify this. Banding stations catch more migrating birds in inclement
species groupings could be constructed?

all means, feel free to revise your past NFC counts to this protocol
(pulling up all your Gray-cheeked records might be a good start, since so
many are detected by flight call).

build this into the system in a way that will best capture the information
and not adversely affect existing eBird output. The hangup is that we don't
want to release something imperfect that will create additional problems.
Thanks for the discussion here.

In any event, I thought it would be worth getting the word out that tonight
seems to be a night for movement of coastal waterbirds. Perhaps Whimbrel or
other shorebirds will join as the night wears on. A full eBird list from my
dusk watch is below.
