Thanks, Ken! If you take a visit out east, these little guys are common as pennies, but they never disappoint with their boisterous behavior and insanely loud calls.
I'd love to get some time with those wren you mentioned, especially the Canyon! I remember trying to photograph some Bewick's out in Washington State, but didn't get lucky that day. We have Winter Wren here, which are pretty much identical to your Pacific variety; also see some Marsh and Sedge Wren here on occasion. House Wren are everywhere here in the summer as well.
