The wren is one of the smallest birds in the UK. It feeds mainly on tiny insects so you are unlikely to see it on your bird table. It is brown in colour, moves with jerky movements and can be recognised by its tail which stands almost vertically. It is a ground feeder and can be seen searching through leaf litter for food. You can attract wrens to your garden by leaving untidy areas around the garden borders with scattered twigs and leaves where insects can hide. In flight they can look like a large butterfly with rapidly beating wings and their song is a beautiful melodic tune far louder than you would think such a small bird could sing. They also often make a 'tick' 'tick' 'tick' sound. The male builds several nests and the female decides which one she wants to use. The nest is made of hair, leaves, grass, small feathers and moss and can be in a variety of places like a wall, bush, tree roots, wood pile or in the case of my own garden a bat box about fifteen feet off the floor where they have nested for the past three years. They nest between April and June and lay between 5-12 eggs which are white with specks of red and brown.
