Imagine this. You’re enjoying a morning brew in your garden.
The blue tits are calling to one another, the goldfinches are feeding,
and the blackbird is staking his claim over the land with his fluid,
musical song. Suddenly, the blackbird’s song ceases to flow. Instead it becomes that
frantic chip chip! – The intruder alarm of the natural world is about.
The blue tits have vanished. Over the hedge shoots a flash of red, a
yellow glint, the barred breast of a sparrowhawk. It’s a scene that
might be familiar to anyone who gardens for wildlife.
