The tiny wren is Britain’s most abundant bird – it is also the third smallest (lightest) only being beaten by the goldcrest and firecrest.
The Latin name for the wren is Troglodytes troglodytes – which means cave dweller – this does not refer to where it nests but its ability to shelter in holes and hunt for insects and spiders within them
For a tiny bird it also has a very loud song – listen here to the classic Radio 4 ‘Tweet of the Day’ episode on the wren.
If you haven’t seen it – I can seriously recommend the book that accompanies the Radio 4 Series ‘Tweet of the Day’ by Brett Westwood and Stephen Moss which is beautifully illustrated by Carry Ackroyd.
This is the book – and here are the details.
