Shot this guy this morning out at a local wildlife area (Yolo Bypass Wildlife Area). The light is kinda harsh, but this is by far the best Marsh Wren for me so far!

Nice calling pose with the open bill. Good sharpness on the important parts - maybe a little off the right and below to move the bird a little away from the centre of the image.
