Andrew,
To me this seems more like a Gray-cheeked Thrush. When I was at Powdermill
in SW PA we routinely got Bicknell's in the fall (~10-20/ year). In
Somerset, PA last fall I recorded several too, but have not fully analized

Andrew,
I like your investigative approach.
Right now the primary evidence suggesting the characteristics of Bicknell's
thrush flight call is still tentative and based largely on the
distinctiveness of "Gray-cheeked" type flight calls recorded in east-central
Florida during spring migration

Mike Lanzone and Andy Farnsworth have worked out a few custom detectors, as
have others on this list.

All,
I can certainly comment on the official eBird position. This has actually
been a topic of discussion for us at Team eBird over the last month or so,
but the NFC protocol will need to wait a bit until we work through some
complexities.
We know that the long term "right" way to enter this
Magnus,
Raven Pro runs on Mac OS X and has an automatic detection feature. There

but I don't think it's as specialized as the oldbird detectors. If you'd
like to try it out, you can get a free 30-day trial license by
