Heard but not seen - a wren

Heard a wren for the first time this year yesterday, while I was in Filnore Woods.  Wrens feed mostly on insects and spiders so they suffer badly in severe winters.  I haven't heard any wrens for months so I was really pleased.

They have a very loud and jolly song with lots of trills.  When they are cross they go "tit, tit, tit" and when they are really cross or alarmed they make a long "churrrrrr" sound. 

Have a listen to the wren's cheery song on Brett Westwoods site listed under "helpful links" on the right of this page below the "blog archive".  The birds are listed alphabetically so the wren is the last one.
