Wren

You will probably hear it first with the remarkably loud song (turn on your computer speakers) from such a tiny bird.  It is rufous brown, plump with a short stubby tail and a pale white stripe through the eye.

In Germany it is called a Zaunkönig which fittingly means Fence-King as you will see it choose a high perch along a fence to perform its song.

It is the commonest UK breeding bird, although it suffers declines during prolonged, severely cold winters.  So what's the smallest bird....? The Goldcrest.
