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

An example of this similarity is shown in the attached spectra and sound re=
cording:
The spectra are of a Bewick's Wren, shown on the left and that of an Easter=
n Towhee on the right. I recorded the wren in Arizona and the towhee in Nor=
th Carolina.
The sound recording is in the same order as the spectra and is of the same =
two birds. The similarity is very close.
