觀察細節
Heard only (picked up by Merlin). Audio captured (attached). The call note of one is heard in the middle of the recording. Its spectrogram looks like a thin, two-pronged fork with the prongs pointing down. The tips of the prongs are at 4000 Hz and the rest of the call note is higher, stretching to at least 8000 Hz.
