The only Bewick's Wrens I have seen have been at Delta Ponds. I think they are such pretty birds. But they are hard to get close to for a photograph. I spotted this one in a tree and was fortunate enough to get some pictures. Also, I found some good information about the Bewick's Wren in the 'All About Birds' website:

"If you come across a noisy, hyperactive little bird with bold white eyebrows, flicking its long tail as it hops from branch to branch, you may have spotted a Bewick’s Wren. These master vocalists belt out a string of short whistles, warbles, burrs, and trills to attract mates and defend their territory, or scold visitors with raspy calls. Bewick’s Wrens are still fairly common in much of western North America, but they have virtually disappeared from the East."

"The severe declines of Bewick's Wren in the eastern United States coincided with range expansion in the House Wren. It is suspected that the House Wren, which frequently removes eggs from nests in cavities, was directly responsible for the decline. The increased availability of nest boxes may have helped the spread of the House Wren, and therefore the decline of the Bewick's Wren."
