This great shot was taken by Len Jellicoe in Surrey, British Columbia, Canada. Nikon CP4500 Swarovski AT-80HD LE adapter Once they get a little older the Marsh Wren has unbarred wing coverts, disconnected buff breast patches, solid dark crown without white streaking, and relatively long bill. Sedge Wren has barred wing coverts, buff chest band connecting across, paler crown with conspicuous white streaks and shorter bill. A Sedge Wren is buffier, lacking that rich brown colour of the Marsh Wren, and has more intricate patterning.
