NOTES: Neotropical Institute Cut # 7. Bulk reel: 229 139 tape. a) Vocalizations by a pair of birds, now perched, but that had been flying around, circling around, one following the other, in an apparent courtship flight. In latter part is Psarocolius angustifrons male in song; apparently two different males @ colony. Quality: 1-2. Level: 0. 3 3/4 copy from orig. @ 7.5; filt. 400/7 kHz (due to motor noise in background). b) A flying "flock": eight birds, grouped as four pair, circling around, apparently "aimlessly" calling. This seems a rather typical behavior. Quality: 3. Level: 0. Other Behaviors: Court.
