5:30 AM. Two birds calling "ao;" near one gives some mild conflict growls and it then flies toward the other bird that was calling. Quality: 1. Level: +8.
Now focused on position where the birds are in an obvious conflict. Voice comments on tape. Conflict vocalizations and some "ao" calls. Flight sound @ end with a peculiar rattle. This may have been an abortive display. Note: At no time was a flight display given. Quality: 1. Level: 0.
5:40 AM. While I was changing tape, one of the birds started giving "courtship growls." Then one bird flew back to position of first bird this AM (with flight scream), then other followed (also with flight scream). This recording continues with mild conflict calls by bird in focus (other bird with "ao"), but apparently there are two birds together and some quiet conversation between them; became silent ~ 5:45 and nothing further heard after that. Quality: 1. Level: 0.
