There is no bird in Britain quite so perfectly formed for causing trouble as the blue tit. At just 12 centimetres from beak to tail, it is small enough to perch on a pencil and light enough to ride a dandelion seed — and yet it possesses the confidence of a creature ten times its size.

Found in gardens, woodlands, and hedgerows across the UK, the blue tit is one of our most familiar and most loved birds. Its striking combination of cobalt-blue cap, lemon-yellow breast, and olive-green back makes it unmistakable at the bird table.

But beauty is only half the story. The blue tit is also one of our cleverest birds. In the 1920s, blue tits in Southampton famously learned to peel open the foil tops of milk bottles to get at the cream — a behaviour that spread across the entire country within decades.

Today, with an estimated 3.5 million breeding pairs in the UK, the blue tit remains firmly in the green on the conservation scale. Long may it continue to terrorise our bird feeders.
