NOTES: Neotropical Institute Cut # 63. Bulk reel: 382
Soft and faint "whiney" calls (given by a female, presumably). Two displays and it's obvious the "whining" bird reacts to these by giving more active and louder whines. She then flies, apparently to join the male.
6:35 AM. Focus changes and another display is heard; then some quiet calls, these more like quiet "ao" calls then whines. There were no more displays after this. Tape: 203. Quality: 2+. Level: +3. Low noise.
Note: 5/III/73 no birds were in this area; some, perhaps these birds, were lower down the slope.
