The Canyon Wren is often found creeping like a mouse around the rock of remote, steep-walled canyons and on rocky mountainsides. The ability to creep around rocks is aided by a low center of gravity, large feet, and sharp claws. The Canyon Wren feeds on spiders and insects, that it gleans from rock surfaces and crevices. The Canyon Wren's vertebrae column is attached higher on the skull than it is on most birds, which, along with a more flattened skull, allow it to reach into tighter crevices. This small bird is often heard long before it's seen.
