NOTES: Songs, initially natural, then after playback of itself, by an unseen bird that was perched 15 meters away and 5-6 meters up in lower mid-levels of good terra firme forest, with relatively open mid-levels and understory, at the intersection of Trails I and 50 North; the first two parts were natural, the second after playback of two songs, the last after additional playback of itself, in response to which the bird initially sang more and may have come in, but subsequent playback had little effect; seen twice by Renata de Melo Valente, but not by me; high clouds, calm, 76-77¡ F.
