觀察細節
In the first attached audio file, in addition to the singing Swainson's Warbler near Bridge 288, you can also hear the distant singing of the Louisiana Waterthrush at nearby Bridge 289. In the second audio file, you can hear both birds singing, first the Swainson's Warbler, followed by the Louisiana Waterthrush. But the waveform pattern for the two species is not the same. Is the Louisiana Waterthrush attempting to copy the song of the Swainson's Warbler?
