Jenny Wren

This is first again I think? 
   I don't remember posting a Wren before? Or if I have,It's a long while ago?
This one was playing hard to get.It insisted in hiding in the reed bed of a nearby pond.I saw a number of them flitting about and thought firstly that they might be Warblers? But eventually one settled in a clear area to give me the shot.
 I think I am right in saying that the wren is Britain's 2nd smallest bird?
