    Equipment Note

NOTES: Neotropical Institute Cut # 6. Bulk reel: 214.
a) Natural song. This is probably one of the birds that was recorded here this AM while I was on ridge south of camp. Prominent in many places are the loud "claps" of the "Bellbird clop" frog. Note: The preliminary soft notes are well heard in many of those songs, especially in beginning part. Quality: 1. Level: +3.
Notes re: cut 6: The main evening song session began 7:15-7:30 PM & ~ 7:30 there was one dislay from each of the main localities and two displays from one or perhaps two localities. There were no further displays all evening.
When the session began, a bird in a same place where bird in first part of this cut sings sang the normal song but without any "vibrato" except a bit @ beginning and end of song. The main part of song was, or sounded like, a "pure" whistle or scream. Unfortunately, I didn't get to record any of this. That bird then changed to "normal" vibrating song and actually it may be same bird as here recorded.
Also about this time a bird planed down from way up the hill and its loud "whoosh" was very noticeable as it planed overhead. It alighted a bit further down the ridge and started singing.
Note: Song activity started to dwindle ~ 8:20 PM, resurged about 8:45 -9:00, stopped ~ 9:15, started again just a little @ 9:30, then stopped completely just before 10:00 PM. Clear, moon.
During the night there was no activity, or at least none that woke me. About 4:00 AM some started and during ~ 1/2 hour several birds sang but there was nothing like yesterday and by 4:45 had dwindled to only occasional song. Activity began again ~ 5:45 AM but no birds sang near to me where they had sung evening before. No displays heard at all until 6:25 AM, when one heard; then another @ 6:40 AM. No others heard. Quality: 1. Level: +3.
b) This is now a new song position. It may be the same bird as in a) on a different perch, although it sounds a bit different. Less low background noise. Quality: 1. Level: +3.
