NOTES: Neotropical Institute Cut # 10. Bulk reel: 204. a) The first sound heard was a "wing-whirr" at ~5:55am (not recorded) up on the hillside to southwest of the place where the birds were yesterday AM and ~200m. away from that spot, across a ravine. Quality: 2. Level: +10. At 6:00AM a bird gave some "screams" and flew and sailed across the ravine toward the place where the birds were yesterday AM (and where I had the parabola pointed). This is followed by a "wing-whirr" from a bird still up at the original site. *Then about a minute later another "wing-whirr" is heard. This is still near the original site but is closer to me. I don't know if it's the same or a different bird. Then this bird flew across the ravine to where the first bird had flown. Almost at once are heard a few "hoarse" calls. After ~30" these are heard again. After a bit more silence the bird starts to call with repeated calls. At first they are more "hoarse" but gradually change to ~"single-note" clear call. b) After the bird became silent, I played the "crows" of P. granti. (I may have played the screams of Cebus nigrivittatus.). After a repeat playing, a bird flew back across the ravine toward where these birds first were this AM and I guess ~ the position of its 2nd "wing-whirr" (recorded). I turned the reflector to that approx position but before I turned on the recorder it had started a "wing-whirr" and I recorded only the second part of it. Note that at end of this there is a whiney-whirring sound that starts before the beat-sound finishes and continues afterwards with a similar rhythm. This sound can't be heard on the other "wing-whirr" but that may be due to level of recorded sound. I don't notice any similar sound on high level recordings of P. marail. However this may be a special sound due to the reaction to playback. The bird then flew and gave no apparent reaction to any further playback. Sound stimulation was (other): "crows" of P. granti. Number of individuals=UU1+;.
