    Equipment Note

NOTES: Neotropical Institute Cut # 11. Bulk reel: 84
Weather: Cloudy, fair. 203 tape.
6:45 AM. Bother calls (presumably) by a bird (female), probably upset because I was by the nest colony. Recorded "on focus" and "off focus" etc. for checking parabola effect. Quality: 1-2. Level: +3.
7:00 AM. Then, calls and song by male. Quality: 1-2. Level: +3.
More song; then sounds of a male displaying and hanging on a nest that a female had just entered.
Calls (by female?); songs by male (He sang whenever a female flew into the tree where he was perched, ~ 30 m from the nest tree; he spent much time perched in this tree.) Quality: 1. Level: +3.
Note: All recordings at the 1973 km 13 mixed colony are filed separately on 7" reel, with corresponding separate editing sheets.
