观察细节
Digiscope video attached - not sure what behavior is going on here - audio isn’t great but you can hear the two individuals singing back and forth to each other in close proximity. The higher-contrast/darker brown/whiter white bird (mostly on the right the whole time in the video) gives a simpler song - was I witnessing a male-female duet/courtship ritual involving female song? Male-male agonistic behavior? I also have an audio recording that I’ll try to get up soon, that is much better than the audio in this video.
