Here is a bit of pertinent dialog between John Hartog and other nature sound recordists
on the naturerecordists Yahoo group.
--------------------------------------------------------------------
This coyote chorus was recorded about an hour before sunrise at a
remote wetland location in Lake County Oregon. Recorded with a SD-702
and NT1A mics. The sounds were fairly distant: I used 60dB gain
setting on the 702 plus 42dB amplification in post to bring it up to
an interesting level for listening. I also put a little eq on the
high end, rolling off about 2dB/octave above 800Hz.

And anyone know what the birds are?

Nice recording John. Could describe the conditions in more detail?
Aside from the great sounding Coyotes I hear the pleasant soft sound of running
water, and frogs?, the cher-cheep sounds like a Western Grebe and finally birds
landing in water. Did I come close?
Thanks for sharing,

Hi Jim,
----------------------------------------------------------------------
Mics about 50 feet back from the edge of a lake. Very slight breeze.
No running water, but lapping lake ripples on fine, silty muck. Arid
environment: this lake likely dries into an alkali flat during drier
years. The lake is irregular shaped about a quarter mile across and
half a mile wide and may be interconnected with other nearby lakes -
and surrounded by dunes 10 to 20 feet high of powdery white dust held
in place by grasses and sage.
I think I hear a bullfrog, but other than that your guess is better
than mine on the callers.
What do think makes the shrieks that seem to get louder with the
coyote chorus?

Awesome!
----------------------------------------------------------------------------
Amazing recording!
What I like, and I presume it is the bullfrog making
the sound, is the way the bullfrog just keeps on
making that sound unmoved by what is going on.
Thanks for that recording and thanks to the bullfrog
for making me smile.

Nice coyote recording, but I'd be very surprised if that was a bullfrog. It
sounds nothing like the booming JUG-O-RUM call that I've heard bullfrogs
make. The consistant timing seems amphibian-like, but the tone of the call
actually sounds somewhat like the low quack of a drake Gadwall duck.
Other birds I heard were Western grebe, Killdeer and Eared Grebe. The
western grebes seem to be the most prominent and react to the increasing
coyote noise.
odd coincidence that I just listened to that recording with my window open,
and now there are coyotes howling outside!

Hey, super cool sounds of the coyotes! It almost sounds like my house
after a siren roars through, must be a canine thing! lol

John,
Nice coyotes! I believe the short "eb" calls in the foreground are
gadwall ducks.

Between what you (Mark) and Kevin have
posted, I hear what you are saying is the drake Gadwall duck.
What I think is bullfrogs is different - down around 400Hz. Here's a
short clip heavily eq-ed to bring out the sound:

I hear this sound all over east of the cascades in Oregon. A couple
years ago Walt mentioned he has heard bullfrogs make similar sounds.
