Sparrowhawks are one of the most agile birds of prey in the UK. They evolved to nip, dive and swerve around trees to hunt in forests, and this means they’re also well-adapted to hunt amongst the buildings in our urban centres. I’ve seen them several times in my garden in urban Cambridge. Either perched on my fence, streaking across in a blur, or, on one memorable occasion, swiping a Starling from the bird feeder and plucking it on the ground.
