[EBB Sightings] Purple Finch in my yard

Twice I've heard a Purple Finch in my back yard. The first time I couldn't see it, the second, I wasn't able to study it because I was holding my binocs in one hand, and a CA Towhee took its place on top of the tree. I couldn't see any obvious red on it, but if it returns I'll try to get a better look.
I recorded it (along with neighborhood noise) on a voice recorder. This is the first time I've heard a PUFI perform mimicry (in between the usual bubbling).
