These are great recordings David. I love listening to frogs and toads chirp=
away. I live in the Buffalo area, so I am near here. The Finger lakes is a=
beautiful area, and big! I am looking forward to part 2 (and 3 ?)
Nice work.

Subject: [Nature Recordists] Spring in Ithaca, part 1
Hello,
I've posted some recordings I took while in Ithaca New York over the
weekend. The subject matter is mostly frogs and toads. These 3
recordings are from the Danby area. I found most of the recording sites
by driving around and noting probable habitats. I then returned at
night, hoping for an absence of engine noise.
For those unfamiliar with upstate New York, the Finger Lakes region is
mostly seasonal forests. The spring and summer are an extraordinarily
lush reward for a long and sometimes bitterly cold winter. There is a
particular environmentalist and conservationist attitude in the region
which contributes to the existence of many state parks and green spaces.
Consequently, there is an abundance of life (and recording
opportunities). I recorded at least a half-dozen anuran species (all in
the same pond), and there are supposed to be even more in the area.
Spring peepers, Western chorus frogs, American toads, bull frogs, green
frogs and gray tree frogs are the species I could identify.
Any help in the identification or correction of species would be
appreciated. There is a comment section for each posting, or
alternatively you can post to this list in response. I am interested in
improving my recording and mixdown techniques, so your collective
criticisms are welcome.
The files are all about 7Mb in size and around 5 minutes in length. I
apologize in advance to those who have slow connections - I really
wanted a long section of the biophony where the listener can hear the
dynamics of the chorus.
All the postings, descriptions, and some pictures and spectrograms are
posted here:

Here are the posts enumerated:
1) A small wetland (West Danby)
<http://unnature.org/assets/2007/5/31/Wetland_in_Danby_New_York.mp3>
Gray treefrogs, a few scattered peepers, green frogs, and crickets.
Recorded about a mile off of highway 34/96.
2) A beaver pond (Danby State Forest)
<http://unnature.org/assets/2007/5/30/beaver_pond_danby.mp3>
Small population of spring peepers, birds (to be identified), and
presumed beaver noises around a lodge. Bees collect pollen from
honeysuckle. The stream feeding the pond gurgles. Please post the
species I have missed. There is a low frequency crescendoing thumping
that begins just before minute 4. I think this is the beaver.
3) Jennings pond (Danby)
<http://unnature.org/assets/2007/5/31/Jennings_pond_at_Midnight.mp3>
Bullfrogs dominate, calling at 40 second intervals. Green frogs. Geese
honk and splash. Bird. Groups of spring peepers. American toads calling
in the distance. A few Western chorus frogs with an occasional quiet low
rumble from a car engine on perimeter roads. There seems to be some
species crosstalk.
Equipment list (for those interested):
- Sennheiser MKH 30/40 MS pair on a shock mount tripod about 5 feet tall
- Fostex FR2LE (48Khz/24bit)
Post-processing:
- High-frequency rolloff beginning at about 12Khz to dampen the effect
of some unwanted high frequency noise due to overzealous trim settings,
mic self noise, and/or inexperience. The mp3 compression used to post
the recordings rolls off some of the highs anyway, but the noise was
distracting in the raw files. Any comment on the correctness of
post-filtering is welcome.
- Stereo Image Munger AU plugin used for MS decoding
Enjoy,
David
