"Whines" by female and ascending whistles by male. Then a display; the whines continue in same place; there's a second display and the whines continue and there are whistles again; then a third display and it can be heard this was by a different bird, as the ascending whistles are heard with the whines and whistles continued.
A display is heard by "distant" bird (actual several, by more than one bird). Then a display, apparently by the bird with the female, as he was seen to come from there and to circle back to there again and his whistles are again heard. Continuation of whines and whistles.
Then another bird arrived and courtship growls (by two birds not [illegible] due to passing vehicle) are heard, then two different displays; then it seems a conflict is developing and that there are probably two males displaying and growling for the female.
Then some "bother whines" (faint) and other vocalizations, including ascending whistles. Then a truncated display: first part "normal, not aborted. After last recording noted on other side I had to change reels and during that time the whistling bird displayed, circling back to "starting point. Then recording begins again: ascending whistles, then a display (obviously in direct line of focus) (another bird giving "aos" is heard in background). Then ascending whistles and "ao" calls by bird that displayed; it had not circled back this time but landed in tree over my head. It then flew back to where it had come from without making a display. Shortly after, it made a display flight, continuing out over my head and down to the cecropia area (cf. cuts 56, 57) and was followed immediately by another bird. Then the two birds were found feeding in the cecropias and some recording of their conversation is heard.
