NOTES: Two females courting one male. Background noise: micro-phone crackle near start, airplane. [This represents primarily the "twittering" described in BNA account, but there are examples of what appears to be the "Zhee" contact call scattered throughout (e.g., 1:24-1:25, 1:35-1:36, 1:41-1:45, 1:54-2:03, 2:09-2:10, 2:15-2:16, 2:20-2:23, 2:29-2:32, 3:21-3:26, 4:21-4:23, 5:11-5:19 (apparently during an aggressive interaction), 5:47-5:49, 5:52-6:02 (another interaction), and 6:18-6:27. Possibly included during these interactions are the "driving flight screams" described in BNA account. Quality changed from 2-3,1-2 to 2, 2-1 - CAM - 18 February 2005].
