NOTES: Neotropical Institute Cut # 9. Bulk reel: 65
Two birds, presumably a pair. There seems to be little difference in pitch between their voices but this may be partly artifact as the parabola is focused on the lower-pitched voice and it therefore tends to exaggerate the high-frequency element of that voice. Also this was after playback and the low-voiced bird's voice may be a bit higher than normal due to stress. Its emphasis is obviously not "natural." Level: +10.
