観察結果の詳細

6:40 pm—dark. Listened to them for about 10 minutes. At least two birds, maybe three. Could only confirm hearing two at the same time as each other, so could only confirm two being present. In the first field off the parking lot. Audio has background noise but contains multiple display flights as well as peenting. Display flights: - One starts at 0:00 - One starts at 0:35 with crescendo at 1:25 - One starts at 2:43 with crescendo at 3:35 Then continuous peenting from 3:50 to the end of the audio, at which point they got quiet.
