观察细节
I pointed my mic at two WEBL hoping they'd make a sound. After staring at me awkwardly for a couple of minutes, they flew off...granting me two soft calls just as they took flight. At 1.1sec and 1.8sec of this recording... The fundamental pitch is at roughly 2.5k. There are overtones at twice and triple that. It quickly ascends and descends, creating a short hill/mountain ^ shape.
