When recorded, these two birds were 50 meters away, 40 meters above the ground, and apparently in the canopy of a huge tree over the road in relatively scrubby terra firme forest on whitish to pale gray sand located 8-10 km out the old logging road where we had been working. [08° 04’ 53.9” N, 61° 37’ 58.4” W, 280 m]. In the fourth and fifth parts of this recording the bird highlighted was perched in the open at the tip of a dead vertical branch in a snag about 50 meters away and 35-40 meters above the ground. Each of these recordings was made after my whistled imitation of the song, in response to which the birds approached and called consistently but only occasionally sang. A full moon was about 30-35° up in the eastern sky. Perfectly clear, calm, low 80s. ML: 75 Hz high-pass scientific filter applied in Adobe Audition CC 2015 to all segments. Equipment Notes: Sennheiser powered using phantom power and with filter in flat position and attenuator off for all recordings. Nagra input set at 2 mV / Pa and low-pass filter in flat position unless noted otherwise.
