I recorded nfc from 2-5am this morning.   Diversity and quantity is pretty good.

At about 2:30am I had a single monotone "whoo" that reminded me of
Long-eared owl recordings (Stokes) except that it was slightly higher
pitched.  Then ~30 minutes later, I heard the same single "whoo" again
except that this was lower pitched and almost exactly matches Stokes'
Long-eared recording, which reduces the chance of night flight.  I
went through all the owl species on Stokes East Coast and still the
only thing that it sounded like was Long-eared owl.

1. Resident owls here are Eastern screech and Great Horned.  I've have
only rarely heard GHO from the location I record nfc (backporch of 14
yr old suburban subdivision).  Immature GHO doesn't ever do a single
"whoo" call does it?
2. I checked ebird and September records of Long-eared owl are very
very sparse in the Mid-Atlantic, which reduces the chance of
Long-eared owl

Any other species that I should check?

Sincerely,
Andrew
