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: http://earbirding.com/blog/archives/774 vs https://ebird.org/checklist/S129533131
