  4. The wren is Britain’s most widespread bird, and is found on almost all offshore islands, and from sea level to the tops of the Highlands.
  5. Wrens suffer badly in cold weather, when prolonged snow cover can deplete populations by as much as 25%.
  6. There are an estimated 7 million wren territories in Britain, making it one of our most abundant birds.

  8. One male mute swan weighs the same as 1,400 wrens.
