Now that the Eastern Rufous-sided Towhee and the Spotted Towhee are
considered distinct species it's certainly worth a closer look. Is the bird
regular at Fischer's feeder? Where is it? Would it be possible for others to
visit, take fotos, etc. I for one would love to add an honest to God
Rufous-sided Towhee to my Washington State list. I don't know that there is
as yet an official record. However, it's not just a lack of spotting on the
back. What of the greater coverts, wing-bars, etc.? Perhaps there are other
differences I'm not aware of, since until the split I must admit I hardly
paid attention. There are vocal differences, but at this season that might
not help much.
