影音備註
Went heavy on high pass filter (1000 hz) due to plane noise. 4 birds in one tree, not certain they were all vocalizing. They were not flying, but uttering what is considerd 'flight call' by Merlin.
觀察細節
Audio attached from 4 birds perched in a cottonwood. Two others heard and seen in another area, all had same Type 4 flight call.
