    Equipment Note

NOTES: Neotropical Institute Cut # 45. Bulk reel: 31
Weather: Fair. Natural one-note song. (NOTE change in pitch at one place.) Quality: 2. Level: +5.
Bird changed position without break in song rhythm.
Then there is a second bird heard giving a dawn song. The first bird continues singing the one-note song.
I tried playback and there was a short reaction of above "dawn song" type (not recorded). Then after more playback a similar but longer reaction after quite some delay. Quality: "1." Level: +5.
Further playback brought no more reaction.
