Nathan's article has a part 1, where he has recordings of the calls of
Winter and Pacific Wren, and says that while at first glance the
spectrogram of both recordings looks the same, the loudest part of the
Pacific Wren spectrogram (where the vertical black line is thickest) is in
the 6 to 7 kHz range, while the spectrogram for the call of the Winter Wren
is thicker at half that frequency (meaning that the bird is louder in that
lower frequency range). The spectrogram of the recordings that I obtained
yesterday appear to me to match Nathan's spectrogram of Pacific Wren:
