    Equipment Note

NOTES: Neotropical Institute Cut # 11. Bulk reel: 37
Weather: Light cloudy. Natural vocalization; birds in distance. Quality: 2-3, 2. Level: +14.
(There's a fair probability that these may be same birds as in Cut 10.)
Bird started with one-note song (3-5 min.) then changed to two-note, then to three-note song. Just about this time a second bird starts with one-note then two-note songs. Note that its voice is lower in pitch and also that the first bird became silent for a short while right after the other started.
Then second bird stops. Then after some time the first also stops with two-note phrases at end.
Perhaps this is a pair.
