The recording was hampered by the continual roar of the 417 which was about 200 meters south. You can hear nonetheless 2 distinct kinds of calls. A buzzing at a pitch of about 3000Hz, which has a distinct 70Hz rhythm. Then there is the higher pitched whistle or squeal. The first few buzzes are at 6.8-7.6, 11.5-12.5, 13.1-14.3, 19.5-21.5, and 23.4-25.5 seconds. The last of these is about 1 minute and 54 seconds.
