I was in general area (@ km 23) ~ 4:45 AM; arrived @ km 21 @ 5:00 AM. Began recording @ 5:05 AM and kept recorder operating "running wild" with the open mike. The first display heard was @ 5:18 AM, across the ravine and up the slope. The first display of "my bird" (at least, that I was aware of) came @ ~ 5:26 AM. The recording first begins just before the display.
a) 5:25 AM. Weather: Fair clear, slight wind. The first display of this bird; it sailed way out over the ravine, then flew back and alighted almost overhead. Quality: 2. Level: +3. 203 tape. LN.
Bird then gives "series whistles." Mild vocal reaction when another bird displays; then this bird displays (inside the tree area). Quality: 2. Level: +3. 203 tape.
"Series whistles" @ new position and a display (note 3-tone sound and series whistle!!) back over mike position, ending in flying to a new perch well beyond. Quality: 1-2. Level: +3.
Display is good.
b)5:50 AM. At the new position the bird whistled a few times but did not display again. The present recording, made with the reflector, is of the quiet talk when the two birds are together (I eventually saw the two birds) feeding in the cecropias. 203 tape. Quality: 2. Level: +3. 3.75 ips. LN.
Note: cf. cut 29 of P. purpurascens for recording that might possibly be of the present species.
[Same recorder and microphone used as in a), but with 36" parabola.]
