    Equipment Note

NOTES: Neotropical Institute Cut # 9. Bulk reel: 204. Weather: Cloudy fair. Single-note clear calls regularly repeated. Birds far away, then "focus" changed to pick them up better and they then change to "growls." Quality: 3. Level: +10. Before these sounds there had been one wing-whirr.
At the point when this recording ends I tried repeated playback of the "crows" of P. granti. I was not aware of any reaction, but then a bird did give a wing-whirr fairly close and on the other side of me from where the bird (or birds) had been. This came unexpectedly and was not recorded.
Note: The evening before I was present from ~5:30 PM to after dark. No vocal sounds were heard that could be surely attributed to these birds, nor did I see them. However, I did hear the wingbeats of large flying birds (not the wing-whirr display). They were probably the guans going to roost. From that general area I heard some rather whiney sounds which may have come from these birds. It was in that same approximate place where I heard the "wing-whirr" this AM, then the sounds recorded in this cut. (Charles Collins was with me both last evening and this AM.) PAS
