影音備註
Normalized to 0 dB with a high-pass filter to eliminate wind and footsteps.
觀察細節
Heard initially flying over, but never saw the group (think they were already behind the trees). Giving their distinct high pitched calls. Later, heard and saw a group of about 30 birds flying off in the distance over Comanche. Got a weak recording of them off in the distance.
