NOTE: this is audio is from a canon DSLR video; the frequency range of the audio from the camera seems to stop at just over 7.5KHz so there is a small element missing from the highest frequency (based on the audio provided by Sheridan Coffey). This has real-time intervals of the second bird that was downstream from the original bird.
観察結果の詳細
Original bird found by Willie Sekula on Nov 08; second bird found by us today. AUDIO: all of the files are lifted from the audio track of videos taken on still cameras. Please open each file at the Macaulay link to see all of the media note details. One of the files has both birds calling. PHOTOS: the first three photos are of what we presume to be the original bird (it was at the location where found the previous day). The next three photos are of the second bird found north of the original bird. I believe that details of the primary tip spacing and tertial edging establish that they are different birds. On Nov 10 multiple birders saw and heard two birds at the same time.
