观察细节
This was a flyby of a group of blue winged teals. It’s barely audible in the recording, but… There’s a soft cap-shaped ^ call that peaks around 5k. There’s an overtone at twice that frequency, peaking around 10k. That’s the blue winged teal flight call. It’s most audible between 2.5sec and 6.0sec of this recording. The call was made by the same group that’s in the picture.
