Here are the final two Bill gave me. They are much longer than the rest. The first one is 32 minutes long, with the second one at almost 13 minutes. I have not listened to them yet since I have not had time.
I'll offer a little description of these two recordings, since Guy hasn't listened to them yet. File four was recorded within sight of Quaker Bridge Road at a vernal pond located about a mile east of the bridge. Lots of interplay here between peepers and leapord frogs; plus some calls of the whippoorwill and pine barren tree frogs can be heard from the distance. The leapord frog closest to the mic goes a bit wild at the conclusion of this recording; I'm thinking a girl frog floated by at the time. This is probably my second favorite recording (of length); it plays well through my hi-fi system at home and helps put me to sleep.
File six is part of a dawn transition recording (or should be; I haven't downloaded these files, but I'm matching the length Guy describes with what I remember sending him). Beautiful sound transitions occur near and in bogs in the barrens at dawn, especially in spring. The portion of a two-hour recording here was made predawn (about 4:30am, on a May morning). Peewees, prominent here, always seem to be the first to awaken and sing.
Thanks again, Guy and Ben, for posting these.
