I appreciate the little cactus wren, but sometimes I forget I'm not one. The cactus wren builds its nest in the branches of cholla cactus, pictured here, a shot I took during a recent outing to Big Bend National Park. It has a distinctive little call--like a miniature crow--a call I'd heard often and hadn't known where it came from. Here's a link about cactus wrens and recordings of their calls from deserts of the Southwest, California to Texas. https://www.allaboutbirds.org
