What I initially thought was a Marsh Wren has turned out to be a Carolina Wren. 

Incidentally, it is arguably the same one found within a 1/2 mile one that was 
present through January and beyond. It has not been seen for a long time, but the 
location would be uncanny. 
I found it across in a wetland directly south of the Buster Dog Park, within Kiwanis 
Park, Brainerd. Crow Wing Co.
