觀察細節
It was a full moon with no clouds and I saw and heard a flock of Tundra Swans fly overhead about 50-100 hundred yards over the tree tops. I took a Merlin ID recording and it also concluded Tundra Swan. I ruled out Snow Geese because I could distinctly hear their wing beats whooshing, I did not see black wing tips, and the calls were lower pitched (compared to SNGO) as evidenced by the spectrogram.
