Wren?

Can anyone tell me what this is? I am thinking wren, but not sure that I am right about that. Anyway, I am going away overnight, so I am posting early. It is a beautiful morning here, and I still managed to squeeze in my walk to the park, but the laundry remains to be finished and the packing. Too much to do and too little time!

I'm off to do it...but not until I thank all of you who commented on my red-bellied woodpecker yesterday. He was quite the poser, and I was really happy to be able to blip him!
