Since they were near the parking lot, there were vehicle/human/dog noises; I cut out one section 1.5 minutes of silent birds/parking lot sounds. Also cut out a noisy vehicle. Filtered at 100 Hertz, but did not use automatic noise reduction, because that changed the sound of their voices.
观察细节
While recording indigo bunting in tree near new structures, two near-adult immature Cooper's Hawks flew into nearby trees, calling. One, probably a female, was larger than the other. Both were calling. They flew to where I could have gotten an excellent picture, if I had had a camera. Audio recording made. Then they flew to the ground where in winter seed has been left. They arrived together, they stayed together and, at the end of the recording, flew off together. The smaller bird had a gray mantle but still had vertical breast streaks. The larger bird was browner with vertical breast streaks. Both had a long two toned gray banded tail with a white tip. The tail was rounded.
