I took wave file 3 and set up a spectrograph of it and sure enough, it fits Pacific-slope perfectly. Your bird is on the left. The one next to it is a Pacific-slope taken from the new Stokes Western Region. The one on
the right is a Cordilleran also taken from the Stokes CD.

I did a web search for "sonogram software" and found several programs that will produce spectrographs. The most commonly used one seems to be Cool Edit, so I downloaded the trial version of it and loaded in the .wav files. I haven't figured out all the options yet, but here are the results of my first pass:
Spectrograph of MPN1, with taped call of Pacific-slope on left and response from our bird on right.
Spectrograph of MPN2.
Spectrograph of MPN3.
Spectrograph of "seet" note.
