NOTES: Neotropical Institute Cut # 23. Bulk reel: 376
Weather: Fair. "Ao" calls. Believe same bird as in cut 22 (but should graph and check). Then a second bird with higher voice is heard in background. Then this bird gives an "ascending series whistle," then a display. Quality: 1. Level: +5.
Change focus to background, higher-voiced bird, which leaves with a "flight scream." Quality: 2. Level: +5.
5:40 AM: Then focus again on what I believe is the same first individuial. "Ao" calls. Then a display. Quality: 1-2. Level: +5.
Note: After the last display above the bird called ("ao") from the new position (which was farther down the slope), then gave another display and apparently went even farther dwon the slope and not heard after that.
