a) Natural calls. Quality: 2. level: +10.
In second section also hear Pteroglossus torquatus.
Then bird closer. This is after playback but the bird had been so far away that I doubt the playback was very "exciting" to it. The bird moved along normally, gradually came closer, then moved on. Quality: 1-2 to 1. Level: +5, 0.
b) After playback that was definitely effective and bird came back closer again. Quality: 1. Level: 0.
This bird was then collected = female #4677.
