On a recent trip in west Texas, I drove by some interesting rocks and thought to myself, "If I were a Canyon Wren, I'd live here."
So I pulled over, walked up to the base of the boulders and began to "pish". Up popped this little fellow. He sang twice, fussed a bit and then disappeared behind the rocks again.
If you've never heard the call of a Canyon Wren, you are missing out. Listen here.
