    Equipment Note

NOTES: Neotropical Institute Cut #37. Bulk reel #514. a) 10:20 AM. Natural song. Quality: 1. Level: +2. 203 tape. LN. 7.5 ips. b) 10:30 to 10:45 AM. This is ~ 100 m. away but is probably the same bird as in a); a good patch of Panicum maximum is apparently the attraction for this spot. Most of this recording is no doubt after playback. Quality: 1. Level: +2. 203 tape. 7.5 & 15 ips.
Note: Although the 7.5 ips recording is good, that at 15 has a "cleaner" sound.
c) 11:15 AM. Now back at same spot as aq); very probably the same bird. Quality: 1. Level: +2.
Bird was then collected = male #[blank].
