Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
Chris Packham presents the barn owl. As soft-plumaged birds which weigh very little Barn Owls avoid hunting in strong winds or heavy rain. Snow is a problem too because it allows voles and mice to tunnel beneath its blanket, out of the owls' reach. But in spite of seasonal perils, barn owls are a welcome sight over grassy fields and verges in many parts of the UK.
