NOTES: Neotropical Institute Cut # 8. Bulk reel: 215; Extra cut length: 12:35; Extra cut length: 7:03; Extra cut(s) on bulk reel: 216; Extra cut length: 5:25a) 7:15 PM 6 March 1969. Natural song, no doubt by same bird as cuts 2, 3 (etc.). Quality: 1. Level: 0. This bird then changed to a different perch where it sang for ~ 6' and then after a delay gave a display. I wasn't able to focus properly for song but the display is recorded fairly well. Fairly clean for sonagram and has second part loud. Quality:1-2. Level: +3.b) 7 March 1969 4:35 AM. Cloudy, fair, moon. I arrived 4:15 AM. No birds singing. By 4:45 a bird started singing across the ravine to south and then what is no doubt the regular bird of this ridge started singing to the west and further up the ridge as usual.It then arrived down over me @ 4:55, sang some, and gave a display. Quality: 1. Level: +3.Then more song from the new position. (5:00 AM) The new position is on the small ridge ~100 m. to south of the ridge I'm on. Some recorded on focus and then shift focus slightly to left. (~ 5:15 AM there is heard a display by one of the background birds.) Quality: 1; Level: 0 & +3.Both song and display good!c) 5:20 AM 7 March 1969. This is really a cont. of 8b). Tinamus tao heard in background, also Otus ingens faintly. ~ 5:20 AM brings an increase in displaying by P. argyrotis; heard frequently on ridge across ravine to south. Ciccaba virgata also in background.Then another aburri was heard to glide by overhead ~ 5:35 AM. After ~ two more songs the bird I was recording flew back over to my ridge, lit down ridge from me and started singing there. It did not display when flying from the one perch to the other.Could this newly arrived bird be a female and the male has gone over to join her? I believe so, see 5d.Quality: 1. Level: +3.d) 5:45 AM. Weather: Fair. Song from the new perch very near to me. (Recorded on focus, this recording has probably the least background noise of any so far, then shifted focus slightly to the right.) Quality: 1. Level: 0.~10' of this off focus recording is eliminated as bird went on singing exactly the same. Then ~ 2' included. (Note that there seems also to be some soft "talk" in here, besides the song.) Then another 13' excluded; recording resumed back on focus (not equally!) then another 5' eliminated.Then continuation of song (with "machine gun crik-it" frog) and note again the quiet talk in background. Quality: 1. Level: 0.~6:25 AM. Then another ~5' eliminated while I changed batteries in the recorder, and with a rare bit of luck got back into operation just before the bird displayed (~6:25 AM). (Actually flew across and out of focus.) Quality: "1." Level: 0.Then is heard some "chicken talk" (this seems to be ~ same as that heard (and recorded) earlier when it was very quiet. I believe this was by the female which must have been the second bird I heard arrive. Then there are some "sucking-like" sounds and it appears the bird flew away giving them. Quality: 2. Level: +5.Note: There were more of the "ascending series whistles" and so I'm inclined to think those of cut 7 were not by argyrotis. Other Behaviors: Perform Visual Display.
