The wren is a paradox of a bird. On the one hand wrens are ubiquitous. They are Britain’s most common bird, with 8.5 million breeding pairs and have by far the loudest song in proportion to their size. They also thrive up and down Britain and Ireland: from the smallest city garden to remote offshore islands. Yet many people are not sure if they have ever seen a wren. Perhaps because the wren is so tiny, and so busy, always on the move. However, if we cast our eyes back to recent history wrens were a mainstay of literary, cultural and popular history. The wren was on postage stamps and the farthing, it featured in nursery rhymes and greetings cards.
