Although we glimpsed this bird once were twice as it flew over the road, we never did see it clearly as anything more than a large shadow passing overhead. When recorded, the bird was perched about 60 meters away and relatively high (20+ meters) up in tall terra firme forest 12.6 kilometers out the main road through the logging concession. The bird began by giving only the more typical, upslurred wail, with the series of hooting notes given following my imitation of this initial vocalization. In response to my whistled imitation, the bird flew back-and-forth overhead several times but we were never able to locate its perch, which seemed to be well back into the forest and in dense growth. There once seemed to be two birds flying overhead, but for most of this, we thought only one bird was involved. We were thrown off at the time by this bird’s apparently having a relatively short tail and its giving the series of hooting notes, which I did not realize the species would give. It was only the following day when I listen to the recordings from Manaus CD project that I realize that this species gave such a vocalization. Mostly clear apart from a few thin clouds overhead, mild breeze. There was a near complete full moon about 30° up in the eastern sky at 19:00. 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.
