Media notes
Edits to the file: trimmed at the end and normalized to -3 dB. Relative to the other recordings, I turned down the gain to avoid saturation, but perhaps a bit too much.
Observation details
Identified by ear by the flight calls and confirmed with audio spectrograms generated from recordings. The recordings below show the most common type 3 flight call variant: a pronounced, zig-zag pattern betwee about 1.5 - 5.5 kHz that lasts about 0.08 seconds. The call starts with a rapidly downward-slurring sound, followed immediately by a rapidly upward slurring sound lasting the same duration, and then followed by a slower downward sound with a "shoulder" about 1/2 down in frequency. Recordings below appear in chronological order.
