December Species of the Month: Wren

Scientific Name: Troglodytes troglodytes


A small bird, with a round body, brown plumage and a signature cocked tail.  Despite its small size the wren has a disproportionately loud call!

Insects & spiders. 



The loud song is used by males to demonstrate ‘fitness’ when defending territory. 

Did you know?

  • Wrens are vulnerable in cold winters due to a combination of their small size and fewer insects available to eat. 

    Research has found that wrens in eastern Scotland are 5% larger than those from the warmer south west of England.  Larger birds have the potential to carry more body fat and may have a ‘thermal advantage’ in cold winters. 

Where can they be found?

It is the UK’s most common breeding bird and is resident all year.  It is found in a variety of habitats where there is good cover and is most frequently found in deciduous woodland.  Wrens will regularly visit gardens. 

Wildlife gardening tips

Avoid using pesticides as these will kill many of the insects which wrens & other birds depend upon.   Don’t ‘tidy’ borders until the spring as this will provide shelter for insects which, during the winter, can be foraged by wrens.  

Grow dense hedges or shrubs where wrens can shelter & forage.
