The difference in the background species of the two cuts is arresting. I attribute it to the repositioning of the bird in response to playback, resulting in my aiming the microphone in a different direction. The first, fainter cut, was unstimulated. I then played his own song (just 1) back to him and he flew close to me and sang.
