These are probably same two birds heard above. There is first natural song by the lower-voiced bird. Then there is song by this bird after playback, but I don't know at which point that part begins (failed to note it in the field due to excitement) but at least the first two songs are natural and I think all may be.
Then there is song by the higher-voiced bird in focus and lower-voiced not in focus. This is definitely after playback for the higher-voiced bird (female?) didn't start singing until after playback. I recorded only one song of this for she stopped singing then. I lost several previous songs by her, trying to find her with the reflector.
Then focus back on lower-voiced bird.
Then this bird was collected (male #5019).
After this the recording was played back again and a bird sang. It is presumably the higher-voiced bird but note its song is now different. I couldn't find it to collect it. (This is type B song.)
