I heard a comotion outside the office. I ran out with my RH10 and a couple of mics
made with EM158s. Unforturately a jet was flying over at the time which you'll hear in the background.

Dawn-chorus on 4-30-2006. This recording was made with the RH10 Hi-MD recorder from a FL III using stereo Shure WL-183 microphones fastened to opposite sides of a mesquite tree trunk. The location was the Clayton Ranch between Brownwood and Goldthwaite Texas. Since it was a little windy I recorded behind the protection of a stock tank dam. At one place in the recording you can hear a wild turkey. Background noise includes wind through the Mesquite trees and a pickup truck in the distance on an unpaved road.
