NOTES: Neotropical Institute Cut # 4. Bulk reel: 203; Extra cut(s) on bulk reel: 204; Extra cut length: 3:51 Weather: Fair. "Whisper song" and whistles. Quality: 1-2. Level: +5. 15 ips & 7.5 ips. (Natural - 15"; natural 7.5"; after playback 7.5".) [Recordist did not indicate type of microphone used. He indicated that he used a parabola but did not specify make/model.] At various times during the day, the night before, and the previous day I had heard the whistles of this species up on the hillside above the road. This evening about 700pm I was on the look-out for owls when I heard a fine little song coming from some trees beside the road. I couldn't see anything and had difficulty locating the sound with the parabola. Then I spied a Currasow that moved from the thick foliage over to a tree at the edge where the foliage was thinner and it remained there in full view, a silhouette against the sky. Being interested in the Cracids, I focussed the parabola on it, hoping to record its whistle. It sat down on the branch and shortly I heard again the "whisper song." It was so weak that I still thought it was from some Tyrannid not quite in focus. But then the Currasow began to whistle. Then after a while it began mixing "whisper songs" with the whistles and after shifting the parabola several times I was convinced that the "whisper song" was actually being given by the Crax. This is the first time I've ever experienced this type of song by Cracids. I later tried some playback. The bird looked in my direction but didn't move and continued to whistle, a bit louder but not with the sharp tone I've drawn before with playback. The whistles that the bird was giving naturally were not as loud as those it normally seems to give. The bird was seen to be a male. Note: 23/IV/68 --> At top of Turiamo Pass, 0550hr, I heard a wing-flap display, then a whistled song. Other Behaviors: Whisper.
