The wren is a tiny brown bird, with a restless nature.
If you鈥檙e lucky enough to spot one, you might see it flicking its tail as it sings out a surprisingly loud territorial advertisement from a fence post or shrub.
They eat insects and spiders, which they find as they hop between foliage and rocks. In fact their scientific name, Troglodytes, means 鈥渃ave dweller鈥�, but they can live almost anywhere from sea cliffs and islands to gardens and parks.
But, you鈥檙e more likely to hear a wren than see it.
Birds make their song using an organ called the syrinx, which is not only extremely efficient at producing sound, but can also produce two different sounds simultaneously.
This goes some way to explaining the complexity of sounds a wren can make: a series of clear, shrill notes, and a familiar scolding alarm call consisting of rapid chittering.
