NOTES: Neotropical Institute Cut # 15. Bulk reel: 402
Weather: Light cloudy. An "alboroto" [uproar; commotion] of many birds. Quality: 1. Level: +2.
Note: See end of Cut 20 of A. ochrocephala for some calls of this species. In August 1970 there were large concentrations of this species in the Rio Catatumbo region (see Cut 16) but apparently relatively few by the Rio Tucuco, where there were concentrations of A. ochrocephala, of which there seemed to be few in the R. Catatumbo region.
