Your gallery has many very good photos of birds. This one is not your best work as it is out of focus. A nice setting, composition and cropping but out of focus. Give the wren another try.
This little guy is so busy that he is holding his head still and wiggling his tail like mad! I like the sun just catching him on the branch, but I wish you had been closer so there was more wren per acerage on the pic than there is.
