NOTES: This was initially natural song (though after a whistled imitation that seemed to have little or no effect) by a bird that was initially 35 meters away and 25-30 meters up; later after playback, it was 25-30 meters away and 25 meters up, always in the canopy of trees at the edge of tall, terra firme forest along the right fork of the second spur (ramal) road in the INCRA project; playback resulted in the bird flying back-and-forth across the road and eventually perching on an exposed branch where I was able to get good views of it (typically it seemed to perch within the vegetation); the song that it gave after playback was similar to that before playback, though songs were given more frequently; the bird began singing just as it began getting light (it was one of the first birds to sing this morning); full, dense overcast with some fog in the treetops, calm, 80¡ F.
