Thanks to a tip from Craig Fosdick, I finally found a Winter Wren this morning at Guinavah-Malibu Campground in Logan Canyon. This species is an old friend of mine. When I was working in Washington, I'd hear dozens of them every day in the Douglas-fir forests where I did my research. Out here in Utah, they're much more rare.
This particular Winter Wren was very interesting because it was a partial albino. In the photos below, you can see the clean white patch above the bill and on the front part of the crown, with a few white feathers scattered back into the hind crown. This is not a normal part of their plumage - this spot should be brown like the rest of the bird. It was an interesting coincidence to find this partial albino bird and a fully albino Northern Shoveler in two days.
