From telemetry work which also involved a micro-microphone, it was found the
thrushes become very vocal before dawn communicating with each other as they
start to descend for the day. One adult female Peregrine we trapped/banded
which had telemetry on it, was found to start hunting way we before dawn
apparently taking thrushes as they descended and actually feeding on the wing
while migrating south through Tennessee. Merlins also exhibit the same
behavior, sometimes hunting an hour before dawn. Migrants may be easier to
take then.

I was up early too. 5 a.m.
It WAS amazing, Jeremy, I agree. Non-stop calls.
I wish I knew my flight calls better but I think many of them were Swainson’s
Thrushes.
I’d love to have the day off to go birding. Have fun everyone.

Good morning,
With the cold front and north winds last night, I thought we would get a good
push of southward bound birds. I also checked eBird, and they were predicting a
huge movement for birds. Sure enough, at 415 this morning while taking the dog
out, I could hear thousands flying overhead. It was quite amazing to hear so
many birds flying overhead. I'm guessing there should be lots of new arrivals
out there today. Good luck!
