Its not a Winter wren anymore… unless you live on the East Coast. These birds were split as different species several years ago. Dividing line is pretty much the Rockies. These guys are bird versions of mice… obviously. 
Most common yard visitor, will go to suet and make nests in weird places around your house.

Very common forest bird, can be found with mixed flocks of kinglets and chickadees. 
Will move in fairly large packs to find aphids and neighborhood suet cages. Listen for lots of high squeeking calls and you will find bushtits nearby.

Listen for their call “Yank Yank Yank” its one of the easiest and funniest calls to learn. I think it was my first bird call. They excavate nests kind of like woodpeckers, with their sharp little knife-bills.
East coast friends: our Pacific wren looks almost exactly like your Winter wren.
