Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. Steve Backshall presents the sparrowhawk.
A garden visit from a sparrowhawk can be an exciting affair. They're smash-and grab raiders, using bushes, hedgerows and fences as cover to take their victims by surprise. Males are blue-grey above, with a striking rusty-orange chest and are smaller than the brown females - this allows the pair to take a wide range of prey.
