The similarity is even more impressive now that I've listened to the
samples. There is a definite 'quality' to the towhee that is distinctive,
but the overall pattern is remarkably similar. Like others have said, the
only Bewicks wrens that I've heard sounded much like song sparrows - very
interesting!

The Eastern Towhee and it's western version, the Spotted Towhee have calls

Bewick's wrens found west and east of Arizona typically have songs that can
be confused with a Song Sparrow. I have often wondered about the boundaries
of this difference in song.
An example of this similarity is shown in the attached spectra and sound
recording:
The spectra are of a Bewick's Wren, shown on the left and that of an Easter=

Towhee on the right. I recorded the wren in Arizona and the towhee in North
Carolina.
The sound recording is in the same order as the spectra and is of the same
two birds. The similarity is very close.
