Attracting Wrens. If this little bird was brightly coloured we are sure it would be declared a national treasure. So donât dismiss the Wren just because itâs small and brown â itâs an amazing songster, cute, fun to watch, full of character and the colour of melted chocolate. Now that sounds much more interesting! Wrens are one of the most widespread birds in the UK found in almost every sort of habitat.
