NOTES: Songs of two unseen birds (duet?) in a decapitated series (quality good but series not complete). Unseen birds were 75 m away and presumably on the ground. Cerrado with pine plantation on opposite side of road. Unclear which habitat birds were in. Conditions same [mostly clear, calm, low 70s]. Mike attenuators on and using Benchmark MicMan Jr. preamp with Sennheiser ME-64 microphone in 24" Roche parabola. Copied with HPF@200 Hz.
