Following Curt's post a few weeks back, I have finally posted some
results from an all-night recording taken at the Upper North Fork
Flowage in Crex Meadows Wildlife Area. The recording was made from Sat
May 1 to Sun May 2 after a day of very gusty winds - this made for
incredibly challenging recording conditions.
Over the course of 12 hours, a great number of vocalizing species made
themselves known to the microphones. Among them are chorus frogs,
spring peepers, sandhill cranes, red-winged blackbirds, Canada geese,
ducks, snipe, woodpeckers of several species, sparrows, grouse, and
even a small mammal. From this full recording I have composited some
aural highlights that are in a rough chronological order beginning in
early evening and ending in the early morning.
The composite recording begins with the calls of chorus frogs and
spring peepers preceding a unison call of sandhill cranes, geese and
waterfowl call as night falls. A small mammal passes the microphones
and a common snipe begins its courtship flights. Dawn excites the
red-winged blackbirds, sparrows, and woodpeckers in the distant forest
to sing as the wind picks up again.

The recording was made with a parallel boundary array using two AT4022
microphones set back from the edge at about 1". Additionally I used a
spherical foam nose between the boundaries. The array was on a tripod
about 2 feet from the ground feeding into an Edirol R-44 field
recorder, recording at 24bit/44.1kHz.
Both Rob Danielson and Paul Dickinson had recording rigs in the very
near vicinity. Rob's post of the evening's recording has a very
detailed timeline of the area including weather, light, and events.
