Andrew,
I don't have any graphical info, but went back and looked at latest fall
recording I ever made (12/3/06). 7 hrs of recording produced just 2 flight
calls, a Golden-crowned Kinglet and a Barn Owl.

I've still been recording 6-8 hours a night and then listening* about
1-2 hours every day. It's down to about 3-6 calls per hour. The
first part of November has been warm here, so that might have slowed
things down some.
How long into fall migration do people record/listen? I don't suppose
