Type A song. Bird brought into song by playing field tape. It did not react to Peruvian O. " "usta", only to Venezuelan O. watsonii, esp. the Type B song. Quality: 2-3. Level: 0.
More of same, after playback of its own song. Quality: 2. Level: 0.
Vocal reaction to playing field tape, type B. Quality: 2. Level: 0.
Notes: a) Bird responded to original playback of field tape as follows:
1) usta - no apparent reaction
2) watsonii type A - sang Type A, but app. remained at a distance
3) watsonii type B - "came in like a shot" but then retired to some distance and sang type A.
b) Later playing of field tape type B song: bird came in very close and sang some type B (not recorded), but then moved farther away and resumed type A. However, further playback of type B brought more type B song, two phrases of which I succeeded in recording.
Two Type B phrases eventually recorded.
