It's a Blackburnian Warbler with a soar throat Walt!

Jesus, you are joking of course! You don't know it, how the hell do you
think us lot will?
I drop out right here, I love the frogs & toads but put me in to
identify them, I'm probably as good as you with birds?

Subject: [Nature Recordists] Mystery Frog

We have had some mystery birds on here, with lots of expert opinion.
Well, I've got a frogcall I don't recognize. Recorded last week in S
Georgia.

Shallow pool under trees, maybe 30 X 50' and not much more than knee
deep. Lots of edge brush. Found during the day with Eastern Narrowmouth
Toads calling. This new guy prefers similar locations to the
Narrowmouths, and must be small, I spent three hours trying to catch one

and never even saw one. More wary than Narrowmouths. They called to each

other's calls, but not the Narrowmouths. And their call is not very loud

at all. It was drowned out completely that night when the Cope's Gray
Treefrogs started calling too.

I've posted a sample that's filtered to remove the nearby lawnmower that

kept at it all afternoon until dark. And I cut out most of the
Narrowmouth toad calls to shorten the original 10 minute recording
(SASS/MKH-20).

There's also a sonogram of a section of the recording before I started
shortening, with the mystery calls marked:

Note I know all the Georgia frog species calls well. This does not fit.
And once before in the same part of the state I recorded a single
individual, but wrote him off as a defective frog. This time there were
more than a dozen, all calling the same way.

I have sent this to my experts, but thought I'll give folks here a crack

at it as well. Bet this one does not get as many takers as the birds.
The wild thought is that it could be a new species, that would be
something fun ;-)
