Nice pic, but you have too little depth of field and some detail is lost. Try decreasing your focal length a bit, and/or increasing your f-stop and slowing your shutter speed a tad, then you won't have so much bokeh on the subject itself. A little is fine, but too much blurs detail. On a stationary eider, a slower shutter speed shouldn't be an issue. And without a busy back or foreground, a little less bokeh is affordable.
